    Good day

    I just want to know which fish eats GHA?

    I know of these; sailfin tang (if they eat)
    Yellow tang
    Lawn mower blenny (short GHA only)

    Paul, many years ago a battled with a lawn of GHA and tried every manner of fish, invert and gogga to get rid of the GHA but with no luck. As a result I ended up with a tank of fish that I did not need and sold as they were only bought to tackle GHA. Moral of the story. Dont get animals to tackle your problems as they may not do what you want them to do.

    You have a nutrient issue with nitrates and phosphates. Guys will suggest DSB's, ATS, denitrators etc. What worked for me was outcompeting the aglae for nutrients and I found bacteria to do this. I used a product called Prodibio biodigest and bioptim and my problem was gone in a month. Guys on the forum must think I'm nuts as I'm always recommending the same solution to nutrients problems but if it works and its cheap, then go for it.

    The other side of the coin is isolating your nutirent problem which could come from many sources like rocks bought from polluted tank and are leaching phosphates into the water feeding the alga, using tap water for top up and make up water, over feeding, carbon etc. You need to isolate the problem and eliminate it to avoid further issues down the road

    nothing wrong with suggesting a formula that works, i too sometimes find myself repeating myself on certain things i have found to be effective

    i agree totally on the treat the cause not the symptom advise.. it will help you gasi better ontroll of your parameters and have the fish you actually want i the system..not having to have a fish in there because you have to :)

    regilar diligent maintenance and testing of water is a good start to find your problem areas. RO water for top ups and finding a good and effective feeding routine that is coupled with good skimming will get you far... as for bacteria additions i am still learning and have had varied sucess but its due to my lack of a complete understanding and proper implementation of a system..

    it is howerver a system worth looking into..

    good luck

    This was just for interest, but yes I do have GHA.

    I have looked at all the posibilities and think it was two things causing it.
    I started up my tank in December 2011 and added fish in Jan but I think I added too much fish too quickly and was also feeding too much. I added seven fish in Jan but is know ledt with 4 I think due to my elephant ear.
    So know the fish is less and and I only feed once a day.
    I bought seagel to remove the phosphates to sea if this is the problem, I've been using biodigest since december and its finneshed now, so I want to see at the end of the month.

    Have you used biodigest on its own or in conjuntion with bioptim or vodka?

    How often do you do water changes?

    I used it on its own and do water changes every week, 50L for a 560L system.

    You also need to turn your skimmer off overnight when adding the bacteria to give it chance to colonise, otherwise the skimmer will just suck most of the bacteria out before it has chance to become active and do some real damage to your algae

    What Tony said...

    In my case i tried biodigest and found it to be useless... I then switched to Special Blend which is the same idea but a different brand of bacteria. The results have nothing short of spectacular.

    You got algae that likes your system, who not give the algae a better home. Just a better spot you would like. See if you cannot set up an algae scrubber. Easier to remove the algae there than in your tank. And on the scrubber they will eventually out compete the algae in your display

    I started getting GHA and got a sailfin and sohal tang it was gone in a week.
    I did not get the fish for that reason but they just ate so that was a bonus.
