Problems with hair algea

Hello All,

I was wondering if anyone had any suggestions/advice about a problem that I have been having. Seem to be getting a fair amount of hair algea (brown/green) in the tank. It is a discus tank and as for plants I have couple diff type of swords and some java fern. Is there any discus friendly hair algea eaters or is this indicitive of a bigger issue.

For parameters, PH is 6.9, kh and gh are about 3 to 4. Havent checked phosphates (probably will tonight). Running a CO2 injection system and almost 400 watts of PC lighting (6700k) for about 10 hours a day.

I have heard many different things about hair algae, most of which the discus probabally wouldnt like.. .you may want to put in some fast growers in the tank to out compete the algae for nutrients, and crank up the co2 (check to see if this is a problem for the discus though)

If you do try to get an SAE, make sure it is an SAE not some of the other cousins, they can get agressive. And I have no idea if an SAE would bother the discus, they are just one of the only fish known to eate red/brush/beard algae

I put 5 SAEs in my 55 planted tank and they didn't start eating hair algae for about 2 weeks. My tank is clear of hair now.

Even the larger SAEs run from my neons, so I don't they would do any harm to a discus. They don't attach themselves to things like otos do, so they should not bother the slime coat on your discus either.

If I had discus I would feel safe putting SAEs in with them.

Sounds like you need:

- more plants
- raise your CO2. At a pH of 6.9 and KH of 3 or 4 your CO2 is only around 11 to 15mg/l. Raise it to at least 25.
- A GH of only 3 could mean a deficiency of either calcium and/or Magnesium.

How big is your tank?
Are you adding any ferts?

yea - twisted the knob on the CO2, see what that does. Need to get a bottle for storing PMDD stuff I got from Greg W. and will start dosing with that. Just using the overerly priced Kent stuff in the meantime. Damm fish keep trying to breed (laid eggs last night and fert them - pretty wild to watch - fish porn ) so going to close off a part of the tank to give the fry a chance (just yum yums to the other fish last two times). Was going to go setup another tank for them but dont want to put the expense out now, maybe if they grow some I'll get a growout tank for them.
