The jbl m001 regulator fit straight onto the fe, I run 3 of them.

Measure the tank as lights come on Cor, this is when the plants require the co2 to be optimum, other than that the method above is correct.

You can add another one way valve between bubble counter and diffuser.

Most plants on your list require gas co2 injection to flourish, liquid carbon can be used in conjunction with gas, it should cover any shortfalls while you get the gas level correct, it also acts as an algacide, always a good thing on new setups.

Quite possibly, at that price I would be tempted to just order and try it, maybe drop a pm to Andy Thurston as a welder he may know.

:lol:

API ph test is bromo blue, add a drop or two to your dc solution and it should make the colour more solid/ easier to read, drop checked solution is just 4dkh water with bromo blue.

The high pressure gauge, as the liquid Co2 runs out the pressure will start to drop, time to disconnect and change the bottle.

Great idea indeed, I used a small power head with a ciggie filter stuck into the co2 tube for diffusion, putting the power head on a timer would've saved a few shrimps lives when I first started out :-(

Hi Aqua, I think Henry used the elite mini to diffuse the co2(run the co2 hose straight into the filter) the impellor will break up the co2 into fine bubbles allowing better diffusion, by putting the filter on a timer say 2hours before lights on untill 1 hour before lights off will act like a...

I have 3 of the jbl regs and have found them solid bits of kit, no issues, what's your working pressure set too ? It may be a bit low to run the diffuser which could cause fluctuations, or a leak somewhere in the system.

If it were me :-) I would cut a section out of the shelf for the co2 canister to sit on the shelf below, you could even put the front section of the shelf on a hinge to slide canister in/out and still sit books in front.

The m602 will fit a fe, din 477 connection, if I remember correctly the tmc came in 2 sizes din 477 and the cga fitting for paintball canisters, as long as you have the din 477 connection, they will be fine, don't think the tmc will run an inline diffuser though, as working pressure isn't...

Well spotted alto, I assumed the adapter to refillable bottles :oops: worth noting that adapter should be compatible with 600gr welding gas co2 bottles, cheaper than aquarium disposable bottles.

The adapted wouldn't work, the u201 regulator is suitable for the pierce style disposable co2 bottles.

You could use a diffuser running into a pre filter as lauris does http://www.ukaps.org/forum/threads/escape.40308/page-3 Something I will get round to trying eventually.

Two dials is probably sold as twin gauge, which leads to confusion, twin stage regs are normally much more expensive and I would imagine you'd have no fluctuations due to temp etc.

I've used that one for a few years now, no issues.

http://www.ukaps.org/forum/threads/cheap-pressurised-co2-system-diy-guide.7696/ Best budget set up I've come across

You can adjust the working pressure of the Reg by removing the small black plastic cover in the centre of the regulator this uncover a hex bolt, with the co2 turned on use an Allen key to adjust the working pressure to the desired level, hope this helps.

Which set do you have ? Newer jbl regulators have adjustable working pressure, my 3 all run atomisers and bazooka diffusers fine.

Not sure how big the soda stream canisters are but I used a bicycle water bottle holder screwed to the side of my cabinet when I ran a disposable welding gas setup.

Hi ovidiu, I've used the DIY co2 yeast method and tbh it was a pain swapping mixtures and a bottle exploded once creating quite the mess :lol: it can be done though, greenfingers journal is a good example. http://www.ukaps.org/forum/threads/starting-point-1st-aquascape.29505/

I've found the jbl filters always burp when u run co2 on the inlet, I think it's down to the design impeller at the top of the filter and gas rising inside the filter.

http://www.misterwhat.co.uk/company/2121403-mr-fizz-uxbridge There you go normally a couple of days turnaround for the refills so I tend to get a few done each time to cut down travel.

I use mr fizz in Uxbridge £12 for a fe refilled

Oh and your substrate will drop your ph to around 6.5 eventually anyway.

Cai, next time you clean your diffuser stick the co2 tube in a glass of water and turn it on for a few seconds, I think you'll be surprised how slowly it comes out compared to the bubble counter, I'd say you are definitely on the right path mate question everything, follow the advice you think...

Hi cai, which bubble counter are you using some have a very small aperture so your 4bps could be less than 1bps with a different counter, it's possible your drop checker is giving a false reading due to the small bubbles dissolving in the dc leading you to believe you have higher co2 levels, I...

You should be looking at the 1 point drop at the start of the photoperiod, when plants need it most remaining steady through most of the photoperiod, not easy to master co2 well, make adjustments slowly then watch the difference for a day or two then adjust some more until your happy you have...

Arrow is pointing to the pressure release valve, as I stated above you can unscrew this and stretch the spring slightly, the Allen key adjustment under the black rubber is the working pressure, as per rebel's question above if new I would return the Reg and have it swapped/ repaired.

Is it coming from the black pressure release valve ? If so unscrewing it and slightly stretching the spring can stop this, ensure you disconnect the reg from the co2 canister first of course.

At least 25 though this can be increased if mods/admin feel your posting just to access the for sale swap wanted section.

Hi amateurfishkeeper, the only silly questions are those not asked :-) 1 a co2 bubble will dissolve as it rises, so we try and keep them suspended in the water column for as long as possible, once it leaves the surface it adds nothing to the water, any bubbles that exit the tank are wasted co2...

Yes I read the story after I had already used them a couple of times, used them for a couple of years now when I've needed refills and so far no problems.

Over near the Heathrow area, I use Mr fizz In Uxbridge Ub8 2eq normally around 3 day turnaround from dropping them off to picking them up.

I have 6 waiting to be refilled mate or I'd take you up on that offer ;-) certainly would consider this though rather than pay for lfs refills :thumbup:

They'd have to be cheap, I can get my FE's refilled for a tenner.

Not how I make a pint of becks but looks good ;):hungry::lol:, try a swan cigarette filter stuffed in the tube instead of the air stone, needs changing every couple of days but much finer bubbles, personally I would carry on dosing liquid carbon to help overcome the inconsistency DIY co2 will...

That's correct a tank full of slow growers like those mentioned above may not even need co2 under the correct light intensity, make small adjustments to your co2 until you feel you have it dialled in for the the plants needs and the livestock would be my recommendation, ensuring you are around...

Ph drop off 1 will occur then plant uptake should make it level off and remain stable, starting earlier at a lower rate shouldn't cause problems IMO I have mine on 4hours before lights and off 2 hours before lights off, Co2 is a fine balance and better to start slower for longer IMO for the sake...

600g welding gas bottle from halfords is only around £18ish think co2art do an adapter, or jbl regs din477 fitting unscrews and screws straight onto them.

Co2 art regs come with standard din 477 fitting George, will fit standard bottles ie fire extinguisher, aquarium specific 500g bottles, you'll only need an adapter to run them on soda stream or paintball or disposable welding canisters etc, hope this helps.

Maybe back pressure/ build up if your solenoid is not closing tight when you turn your co2 off, I had this with a heap solenoid I bought it would let co2 through for maybe half hour after I turned it off.

Can create problems, plants become accustomed to co2 levels, you will need to back the co2 off slowly whilst reducing the intensity of the lights to minimise impact on the plants IME, you can also use the dry start method to increase plant mass depending on the type of plants your using, keep...

Surely the pressure is regulated by the working pressure of the regulator not bubbles per second/minute, cheaper diffusers ceramic plates are hit and miss IMO some fine bubbles some very large and I've tried a few, keeping them clean always helps get the best from them IMHO, also the addition of...

:lol: wet floor :oops: 15 seconds may be better with that beast of a filter, then just do the maths :thumbup:

I would recommend cleaning the diffuser with bleach, soak it in bleach and use a syringe with some airline attached to push bleach through the diffuser, then soak in strong dechlorinated water solution and push this through the diffuser with syringe, the diffuser may work more efficiently once...

Fill a bucket or jug from the filter and time for one minute x 60 you have flow in liters per hour.

It's baffling sometimes, you do seem to have all the bases covered, flow co2 not extreme lighting, just have to keep at it mate, it's a nice looking scape by the way. Also fwiw I use london tap hard water and two different scapes in the same tank, first scape ph drop was from 7.8 -7.1 healthy...

Do you have surface film on the water at all ? Fwiw I couldn't get co2 right on my 90cm Untill I added a skimmer, IMO even a slight film traps unused co2 ie at the surface not the substrate and it builds to unhappy levels, surface skimmer alows this to gas off, wasteful but better for livestock...

I think it degrades in the tank due to light, hence most liquid carbon products I've used come in white plastic bottles not opaque.

It's well worth exercising some patience and having a good read of some of the tutorials and sticky threads re co2, when you feel you have a good grasp of it you'll save a fortune.

http://www.co2art.co.uk/products/aquarium-co2-dual-stage-regulator-and-solenoid-magnetic-valve has had good reviews from a few members on here, use co2 fire extinguishers or rent pub style bottles for gas supply, I get through 2kg gas every 6-8 weeks on my 180 ltr tank, the disposable jbl set up...

Yes gas will want to rise, if the power head position isn't optimum it could be out of the tank rather than being pushed back down.

Always more efficient to have the 10x flow from one source IMO less chance of conflicting flow patterns.

Try soaking in some white vinegar, it may be blocked due to limescale.

I regularly use mr fizz not the fastest turnaround but @£10 a refill it's worth the few days, never had an issue with the refills.

He has a way with words :lol:

I position mine wherever it's easiest to read, as you said it's just a guide.

Maybe the bottle change increased working pressure and the efficiency of your inline atomiser ?

Plenty of threads on the forum about amanos lighting and I'd have to agree its low to medium, massive pearling really healthy plants or a massive water Change pre photo.

A good soak in white vinegar can help remove hard water buildup after the bleach.

Which reactor would you recommend Iain, I'm thinking of trying a reactor on my 3ft tank next scape, consistent co2 has always been elusive using an atomiser in this tank.

Hi john, I have two of these regs I run one at 3 bar it runs perfectly the other at anything above 2 bar vents gas from the pressure release valve so not so perfect.

I've used the extinguishers from a eBay seller based in Staines, faultless so far, fairly speedy delivery and never a problem.

May as well ime, plants are like addicts and some will melt but with lower light it's surprising what survives sometimes, I've only done this once though but even the crypts didn't melt.

Cut lighting, turn off the gas and trim any melt as it happens coupled with regular water changes Untill you see new growth again.

Also worth making sure your reg has enough oomph to run two high pressure diffusers.

Well I use good old London tap, which is hard water :-) normally run my co2 on 2-3 hours before lights on and off 1-2 hours before lights off depending on tank and I always have a lime green d/c at lights on though this can be misleading if using inline atomisers IMO, reactors I've not used so...

Looking at your profile though, I'd say you can increase injection rate or improve distribution 5 hours pre lights could be improved on, IMO make your adjustments slowly over say a couple of weekends if you can't increase the injection rate it is probably a flow/distribution of flow issue.

I don't own one but have read you need calibration fluid to set them, may be why you are getting fluctuating/ inaccurate readings, I think you can get the calibration fluids on eBay.

Are you calibrating your ph pens ?

You can also try staring co2 earlier 2 hours before lights on off 1 hour before lights off is what a lot of folk on here run, plants really need optimum co2 at lights on, mine runs 3 hours before lights on off 2 hours before lights off, keeps fish and plants happy.

Agree with enderuk, mine comes on 3 hours before and off 2 hours before lights on my 3 footer, best to have it optimum for lights on and used up by the end of the photoperiod for the health of your livestock IMO, when I ran it to an hour before lights out my pencil fish would sit at the...

I would personally just stop the easy carbo and see how good my co2 is, if the plants sulk it not as good as you think it is :lol: reduction in light slightly can also help in weaning them off.

I'm using a couple of the ones you linked troi, spot on IMO fine mist and cheap enough to buy two to swap between cleaning.

The fluval bubble counters are good IMO work fine with 3 bar pressure on my reg, seemed a lot of bubbles when I switched from the jbl reg but bigger hole size etc etc, with co2 you have to hold your nerve longer than you think you need to and make sure your around to aid livestock when you...

Your adding less co2 than you think you are, or less than your plants need but don't add too much because your livestock won't tolerate it.

Hi john, I have two of these and can't fault them tbh, they are single stage regulators though so end of tank dump is possible, though not something I've experienced in two years of use with the jbl cylinder or co2 fire extinguisher as co2 source.

Keep an eye on flea bay gumtree etc etc see if you can pick one up second hand.

Most regs in the £50 ish price range won't have the best needle valves I use two of the jbl's and can't fault them ( I've sold off other regs I've owned)

Buying a new fe each time works out cost effective compared to the cost of a 500g refill through lfs :-)

Buy the extinguishers full off eBay, normally for only a little more than the cost of a refill from your local ma, then once empty find a local place to refill normally around a tenner.

I'm using two of these good regulators IMO if a little expensive, the m602 will give you the option to switch to a larger canister (co2 fire extinguishers) fit when your fed up of waiting for them to be back in stock at your lfs.

Ha they wouldn't know what potassium nitrate was, you'll get there jafooli, ukaps made me I've only been in the hobby 3 yrs I put all my faith in Clive, plantbrain, and all the other wonderful ukaps posters and I haven't looked back.

You will find lfs will try to baffle you with bulls!!t constantly, I like to do it back to them :-) seriously fish is a good point of call for species research mate, ime even if you have a semi thriving planted tank you'll give your fish a better environment than the lfs tank they came from...

Tbh the guy is full of s!!t if he was keeping Corries responsibly his ph would be much lower than 8 lol, as Clive states co2 is most important at lights on in my 90cm I have to have it on 3hrs before lights but it goes off 3 hours before lights too, play around with injection rate timing etc...

The co2 art inlines www.co2art.co.uk/store/diffusers-reactors/aquarium-co2-atomizer-system-diffuser-1216mm-hose/ very good product and value for money.

Ah ok good, yes ceramic diffuser will be an improvement, also worth mentioning if you run an external filter the jbl regs have adjustable working pressure so are more than capable of running inline atomisers, I run two of these regs at the moment with atomisers from co2 art (sponsor) very fine...

Hi Chris, is it the gas co2 kit or the yeast version ?

Sell it too me :-)

You can use an atomiser like that as long as your regulator has adjustable working pressure, similar atomisers are available from aqua essentials.

The boyu inline diffuser will work under normal reg pressure Claire, can be a bit hit and miss on bubble size though, the fluvals are good for an in tank diffuser though can be a pita to reseal after cleaning.

You need to mix the low range ph liquid with 4dkh water. As Andy d stated just crank it Henry until you can get the 4dkh delivered.

Try sticking the co2 tube straight into the inlet, sometimes easier for the big bubbles to be smashed up, where the small bubbles accumulate, keep a close eye on the tank if you have livestock though mate better diffusion can lead to disaster.

Not sure what happens tbh, just based on my experiences over the last 12 months or so, I recently added some beckfordi pencils to my 3ft tank they all settled nicely apart from 1 which stayed at the top until I raised an outlet slightly, I do think certain fish tolerate co2 levels better than...

May take them some to time to adjust, I've found a little stronger surface agitation can help.

Brush the washing up liquid/ water mix around all your seals, check valves etc then watch for large bubbles indicating a leak.

I used this method for around 6 months with no issue there are a couple of you tube vids if you google diy co2 cigarette filter, cheap and cheerful method IMO.
