Same issue for years with my tank, but I sorted it by changing my CFL tube from 6500K to 4000K no diatoms now. Cheers Paul

The support legs on the lighting unit are not long enough, so the light intensity is to bright due to distance between the lighting unit and the top of the water / tank. You need to reduce the light intensity either by the controller if there is one or lift the lighting unit up. Cheers Paul

I would start to add some Easy Life Nitro as well as the above. No Nitrogen or potassium is been added which it vital to good plant growth. Paul

Algae is caused by not get the balance between the following: fertz / lights / Co2. Your tank has slow growth plants so you dont need masses of light, 5 hrs would be fine and one lighting period - splitting the period 5.4.5 does not help. Plants consume fertz during lighting period so they...

No - reading through one of your previous thread https://www.ukaps.org/forum/threads/algae-identification.58371/ you have altered your lighting period, changes to Co2 and the algae has gone. Excessive ligthing is the route of all evil algae. I had a diatoms issue for years and it disappeared...

Tank spec's would help: tank size - how many litres, what filter inc. flow rate, fertz regime, Co2 - yes or no, the big question "how much light T5 or LED and lighting period - how long. Im going to say your lighting is to bright and the lighting period to long.

here lies the issue https://www.ukaps.org/forum/threads/4ft-tank-1st-in-5-yrs.58007/page-4 with your algae.

Your have got more wattage over that tank than my car headlight have as standard, your issue is lighting way to much. Lift your lighting hood up if you are using one, if not reduce the wattage.

Arh now we have a better picture of whats going wrong - the key thing to getting a correct diagnosis of algae issue is giving all relevant information ie tank position, lighting, fertz, planting regime and contents of aquariums.

The issue is the strong afternoon sunlight - so move the shrimp jar so it not in direct sunlight if you cannot physical move it put something between the window and the jar to stop the sunlight getting ot the jar . Cheers Paul.

Hi Looking back through your previous thread postings https://www.ukaps.org/forum/threads/first-aquascape.58314/. Lighting is your problem too bright and too close the water surface. LED lighting is bright (intensity wise) you need to lift up the lighting unit ie suspend it from the ceiling on...

The lights are to bright - can you lift the lighting unit up that will reduce your lighting intensity, say 12" from the top of the water Paul

Danny turn your lighting period down to 5 hrs, double you dose of liquid carbon, triple does your fertz, 50% water change every week and buy some shrimps - let everything settle before you add Co2. Paul

LED lighting is bright - bright light = lots of fertz + lots of co2 + good flow. I would incease fertz regime to 15mls and reduce your lighting period to 5 hrs and monitor plant condition if possible raise the lighting hood up to reduce the intincity of the lights say 12" from the top of the...

Ian Well I have to disagree - been running like this for 12 mouths with no issues at all. Depends which Neutro or Tropica fertz your purchase. Tropica Premium & Neutro T fertz is just a trace mix - for low tech tank with out Co2 hightech tank with Co2 injection. Neutro + contains trace...

James How many ltr of water does you tank hold. Paul

James 5mls of fertz does not seem a lot - could you advise on the fertz you are using. I use E.I for my 60 ltr tank, but I treble the quantity of dry salts used in my mix, but reduced the amount of mls added daily to the tank by 1/3. This is what I was refering to when I said tweeking your...

James What quantity of fertz are you dosing at the moment. I too dose with E.I but I mix my fertz to what I thing is right, I started off low dosing and tweeked my fertz to suit and I dose my NPK & trace on the same day not alternative days and its worked for me. Paul

James Could you advise of the lighting period - if its greater than 5 hrs especially with LED lighting as it very bright - I would turn down your lighting period to 5 hours max. High lighting Inc. excessive time period trips the algea into growing ( that my view), so balance your fertz + co2...

Hi Ross There lies the problem. I have tried and it does not work - well didn't for me. My idea was to get an established tank full of tank than add fish but I ended up with diatoms. Get some fish / shrimps in there it will help removing the algae Paul

Thats what I plan to do next. Paul

Quick up date - all diatoms g Quick update - change CFL tubes from white / red to 6500K day light CFL tube which are brighter, also increased my EI fertz regime and the diatoms has disappeared, Co2 injection still switched off. Paul

Same issue as yours - but mine started as I injected the Co2 - still dont know why it happened. Paul

Adam Please advise whether the lighting unit is T5 or T8 tubes and the lighting periodicity (how many hours). Paul

Oh "NO" Dolly Sprint was not joking - Co2 switched off and diatoms is dissappearing - Neil you were correct in your remark Paul

Co2 has been turned off - see what happens. I have my suspions that the ligths I am using AquaOne white / red CFL x2 - the red spectrum is causing the problem Paul

Guys Out of all my tanks 3 off - 2 previous (no longer have these) and 1 new one (current), I have never ever encounted Diatoms until now. The tanks is 60 ltr (Aqua mode 600) eheim pro 200 external filter, lighting period 6 hrs total wattage 22 watts (aquaone tubes), full E.I ferts, Co2...

We all know that excessive lighting period can switch on the algae into growing - I have read the above thread replyies + Initial posting and there is no mention of the lighting periodicity. Regards paul.

Hi Always worth while whilst doing your water change give the substrate a light hoovering with a gravel / substrate cleaner. I would give the substrate a good hoovering where the BGA is present. AQUARIUM FISH TANK GRAVEL CLEANER MEDIUM | eBay I give mine a quick hoover every time a do my...

or increase the distance of the lighting hood to the tank substrate - from you initial thread I think you stated 16" try 24" and then decrease if required. Regards paul

Hi Could you advise on the lighting periodicity - how many hours. Regards paul.

Hi Greenview Have a read at the attached: http://ukaps.org/forum/viewtopic.php?f=19&t=19834 Regards paul.

Hi Its like walking on a tight rope - one wrong footing - your off the rope and the tanks the same. Hit the sweet spot and your laughing - any tweeks that you do, remember what you did as you can revert back to original set up and tweek one thing at a time. Regards Paul.

I've had algae growing on my ceramic diffuser plate and any plants directly infront of my spray bar or where the flow was high were prone for BBA - swapped to a lily pipe - no futher issues. Regards Paul

Jon The problem is stated above - low tec tank running with a very high lighting period 9 - 10 hrs - T8 light is ok for low tec. Turn you lighting period down 5 - 6 hrs is fine. its an old picture -my tank get 6 hrs lighting max Regards Paul.

Guys have a read at the attached: http://ukaps.org/forum/viewtopic.php?f=37&t=7452 & http://ukaps.org/forum/viewtopic.php?f=19&t=9851 Regards paul.

Hi Try and aim for lime green colouration @ the start time of the lighting period. As for the gasping fish, if you slowly tweek the quantity of gas been added the fish will acclimatise themselves to the high level or turn the lighting period down as 9 hrs is a lot - oldish picture attached of...

my drop checker turns lime green about 4hrs into the photoperiod Ady You need to aim for a lime green colouration in your DC as soon as your lights come on. if you have your Co2 solenoid valve on a timer, adjust the timer to switch on the gas 1 hour prior to the lights coming on and tweek...

Niru Any chance of some picture - we then can provide a better diagnosis of the algae and what action to be taken, how long is your lighting period and for 180 litre tank i I would be running with a high co2 injection rate than 2 bps unless you are running co2 24/7. Regards Paul.

Lee try MA @ Derby or Rutland http://www.google.co.uk/url?sa=t&source ... 61asDD4qeQ Regards Paul.

If we new the above - we would be laughing :D but we don't know so by adding a quantity of fertz and then watch what happens to your plants - if there is no improvement in plant growth or better condition of plants or the algae has dissappeared its no enough so add some more. Regards paul.

I would start dosing 1ml per day and increase if required - the way of finding out whether you have hit the sweet spot is by looking at your plants ie condition of the leafs + growth rates. Regards Paul.

Hi Five hours running 2 x 24 watts T5's should be ample - HC will melt or transform as soon as you emerse it into the water, its grow as a semi aquatic half in water (the roots) and the leafs above water, you should have seen some transformation once you planted it. N.B High lighting...

Hi and welcome to the forum. Your Co2 levels within the water column seems reasonsably @ 25ppm - I'm assuming you are using a drop checker to indicate your co2 levels within the water column then comparing the colouration against a co2 chart ? - try and aim for a lime green colour. As for fertz...

The above is your problems - I would try to move the direction of the flow from the affected area and as Clives states "improve flow" as for liquid carbon I would not be too concerned about the amount been added - direction on the bottle state 1ml per 50 ltr and a maximum of 2 ml per 50 ltr - I...

Gareth You could increase your liquid carbon dosing / invest in a co2 kit. Regards Paul.

Hi Pesty Thx for the reply - i would turn your lighting period right down - 5 hrs max, as for the pressurised issue why dont you do a DIY mix - yeast, suger etc in a pop bottle, it wont be as good as a pressurised system, but at (yeast oop's) least your add some co2 gas to the water column...

Hi Pesty happy new year to you. Could you advise as to "how long you lights are on for" as excessive or long periods of lighting will switch on the algea, are you adding any liquid carbon and I think you'll have to invest in a Co2 kit. Regards paul.

Pauld if in doubt about the colouration of the DC - take the DC out of the tank and place infront of a piece of white paper, as for the bubble in the spray bar - can you lower the spray bar and twist it upwards a little, the problem is that the hole in the spray bar is lower than the residual...

Hixy As per our conversation on chit / chat. Regards Paul.

MZM Yes - ph controller is your problem, the controller measure the ph within the water column and if a drop in ph is registered the co2 gas is switch off which will cause fluctuations in co2, you would be better off removing the controller and observing the ppm of Co2 within the water column...

Lil Looks like Blue Green Algae or BGA - its the second item of James's list. http://www.jsctech.co.uk/theplantedtank//algae.htm Regards Paul

Mirf See if your local fish shop has some of these - these little guys will clean the diatoms for you. http://www.aquahobby.com/gallery/e_oto.php Regards paul.

Mirf What are you doing different from when it disappeared and now - you must be doing something different to trigger the algae. Any pictures - Regards paul.

Mirf Could you please advise regarding the quantity of light - how many watts and whether they are T5 or T8 as the intensity of light will trigger the algae to start invading the tank. Regards paul

Dmense The 10 x the turnover is filtration / circulation, you will not be able to find "A" filter that will accomplish the 10 x the turnover of water - this why the guys / gals on here run with "TWO" filters units or one filter and add a or two circulation pumps Hydro Korilia are a favourite...

Hi and welcome to the forum. Sorry for being so prompt - but if you don't nip this in the bud you are going to have major porblems Probably causes of algae: To much lighting and too long a lighting period 300 watts for 8 hour 500 litre of water - hourly turn over should be 5000lph Co2 3 bps...

Hi Gollum456 With the size of your tank you should be injection more than 3 bps - have you moved the DC around the tank to see whether there is parity with the colouration. My instinct tells me that your Co2 levels are not high enough, lighting periodicity it too long, not enough fertz being...

Peter One thing I have noticed with your stats - two lighting periods, it would be advisable to have one period only, on at 15:00 and off at 21:00. Your plants will start to photosynthesis when the lights are on and then stop when the lights go off and start again when the lights come on again...

Hi When you refer to cloudy water - are they particals within the water coloumn, my initials thoughts are that your fish may be distrubing the substrate, the particals then float upwards and are pushed around the tank in the water flow and when looking at the tank is looks cloudy. Regards Paul

sWozzAres Please see attached shorcut to the different types of algae that can occur in a planted and what you can do to combat the affected areas. http://www.theplantedtank.co.uk/algae.htm Note: Diatoms is usually found in new tank set ups. Regards paul.

Oliverar Four item contribute to Green Water: A) High lighting B) High ammonia (nh4) C) Imbalance of Nutrient levels D) Disturbance of the substrate I think we can rule out "A" as the only plant you have in the tank is a moss, "B" is a good bet, "C" could be a possablility and "D" is a...

Hi I agree with the above quotation from Chris :thumbup: and 9 hrs of lighting seems quite a lot - if it were me I would knock at least 2 - 3 hrs of the lighting period. One thing I do is to clean or vacuum the substrate prior to where the new plants are going to be planted. Regards Paul.

Hi Andy advise is spot on and I would like to add a 4th if i may, buy some little otto's as they love to eat brown algae which is diatoms - diatoms usually appears in new tank set ups. Regards paul.

Phil Could you please advise as to your Co2 levels, tweeking co2 levels will help in removing the algae - make sure that your fish don't suffer. Regards paul

Tennis4u Brown algae looks like diatoms which usually appears in new tank set ups, little ottos will clear that for you. As for the green algae - increase Co2 levels and keep dosing the excel, try dosing just the infected area and you need to purchase a glass drop checker with Co2 reagent fliud...

Trevor Increase quantity of water change to 50% once a week, there are a lot of forum members that do a 50% wc every week. Regards Paul.

My personnel view is not enough fertz for your tank. i would at least double / treble your daily dosage. Regards paul.

To clean my pipes I use an Ehiem set of bushes - various sizes of brushes on a nylon pull cord and Morrison Baby Sterlising solution to clean ceramic difusers Regards paul.

I run this tank on 6 hrs of lighting. Regards Paul.

Personelly I would knock two hours of your lighting period and have you decided which algae you have: http://www.thetropicaltank.co.uk/phpBB/ ... 8bd8962ebd Regards Paul.

Algae will always attack no living or poorly / weak item eg. rocks bogwood and plants that are properly looked after ie in-sufficent fertz. After looking at your lastest pictures there is green algae on the rocks. Several questions. 1. What fertz are you adding 2. type of lighting T5 or T8...

Thats all the glass even below the water line - right down to the substrate :thumbup: Regards paul

The main problem that causes GSA is high lighting - turn your lighting period down it too long especially when using T5 tube - knock it down to 6 hrs max with two tube Inc 2 hours (mid lighting period boost) with the other two tubes on, wipe all the glass with GSA on it when you do your water...

Personnel view turn your lighting period down to 6 hrs per day as the syptoms you are suffering from indicate too much light - T5 have a high output and dont distrub the substrate when doing water changing. In addition to this I would start doing a 10% water change every day for a week Inc. the...

How long are your lights on for - if you have a long periodicity of lighting this could be your problem. Regards Paul.

Can you supply more info - tank size, filter type + flow rate, how many lights T5 or \T8 & how long they are on for, daily fertz regime, how often water is changed etc. Regards paul.

Could you please advise as to how long your lights are on for. Long periodicity of lighting can contribute to GSA as well as high lighting. Regards Paul.

Andy Have a read at the attached shortcut may be helpful: http://www.thetropicaltank.co.uk/phpBB/ ... 1db90232eb http://www.theplantedtank.co.uk/algae.htm Possible culprit - no fertz being added that if is a planted tank. Regards Paul

Zigur Lighting Lets sort your lighting out first: 8 hours lighting periodicity @ 2 x30 watts and within those 8 hours a 1 - 1.5 hour burst with the 2 x 55 watt - exccesive lighting or long lighting periodicity will promote the growth of algae. C02. You need to buy a solenoid valve and a 12...

Its just a case of getting the right balance between fertz / lighting / Co2 - hit the sweet spot and you are laughing. Regards Paul.
