That's a bad crack! Won't be messing with mine too much that's for sure!
She was unlucky but it was caused by bad handling i added it to show that there at there most dangerous with no horn on
So handle with great care, a small discharge could remove fingers
Right the time has come to start my CO2 FE set up and have been looking at purchasing all my supplies to get going. This is what I'm was going to pick up to run in a Jewel Trigon 350. Before I push the buy it now button I wanted to double check with everyone here that I am indeed buying the right stuff for the size of aquarium and if I'm missing anything important.

and a FE and tubing as well
Thanks again Ryan

These regs look ok if you wanted it in ££££s
Thanks Oldbloke I actually put the wrong link down for the reg. The guy who's selling all the other bits I need has the same one, which is nice to get it all from one seller.
Can anyone see if I'm missing something glaringly obvious or have I covered all the bases?
Drop checker + fluid ?
This is what you're talking about right?

Maybe this is a stupid question, but can I run two tanks CO2 from one FE system?
As long as you want the same rate in both tanks I would see no reason why not (IMO)
Yes you can buy using a splitter like below this way you can run different bubble rates

Thanks loads. Will start making my shopping list
I'll get me coat.........
Like above but put a spray bar in each tank. You will need two needle valves etc so that you can adjust flow to each tank. If you use just one off tee'ed to two tanks the CO2 will take the path of least resistance and basically end up going in just one tank.
Is that a fish in the bubble counter?
thats what i was thinking
Just had to replace my first 2kg FE, it only lasted a month and a half! I was expecting it to last much longer than that.
In a 200l tank on for 6 hours a day. Is that normal?
On my 180litre tank I got the following from my 2Kg FE's.
1. 255 days.
2. 137 days - Leaking from cracked bubble counter.
3. 60 days - Leaking from bubble counter connections.
4. Currently 49 days old, CO2 still sloshes around inside, so quite a lot left. Unfortunately a very old cylinder (Aug 2003) and when full, weighs over the 5.5Kg my scales can measure, so no idea how much left. A modern FE cylinder with my regulator attached is 5.38Kg going down to (obviously) 3.38Kg when empty.
I have 180l tank with JBL bubble counter running 1-2 bubble per second, for 8 hours, using UP inline diffuser and drop checker green at lights on.
- could have a leak, which is why my cylinders 2 & 3 emptied so quickly. Only realised no. 3 had a major leak when FE had emptied so quickly.
- too much surface agitation, so loosing gas.
- poor CO2 diffusing method.
- Supplied with a non full tank !! (full weight is stamped on side 4.85Kg on the one near me at work).
cheers for the info thats helped.
Could be a leak some where?
co2 is dissolved by diy reactor.
very little surface agitation so ruling that out.
I dont use a bubble counter, co2 tubing goes straight from the solenoid into the reactor via 1 check valve.
I bought the FE online form a fire extinguisher company but it was a refurbed one and didnt have a weight stamped on it?
I'll check the connections for leaks.
It should have the weight stamped on it, like this, 4.87Kg.
This is how to determine, during inspection, how much gas is in the extinguisher.
Must also have, by law, the manufacturer/inspection house, serial number, the empty weight (tare), full weight, CE mark built to, test and burst pressure and date of manufacture/last inspection. Fill pressure is not needed as normally constant 55bar for CO2.
My first check valve, after starting CO2 setup, leaked after a month or two. This was an air check valve and the plastic went "misty" and it leaked CO2 at the seams WHEN bent slightly. So first dunk underwater for leak testing, nothing all. Applied slight force to valve and bubbles streamed out. Also the internal rubber diaphragm appeared to have melted/distorted.
I now know this is due to CO2 attacking the plastic and dissolving in rubber and I should have been using proper CO2 proof valve. I know have a UP CO2 one way valve, the one with locking nuts.
