Green Cloudy Water????

[icediver]

I have a 55 Gal Tank That I keep getting a green algae bloom in!!! There is no direct sunlight on the tank!!! I also use R.O Water!! The only fish I have in there are 8 Jack Dempsys. Any Idea on a fix for my tank?

Welcome to AC! :)

What kind of filtration and what are the water parameters?

[wetmanNY]

It's an imbalance: too much nutrient, too few planktonic grazers eating those single-cell algae and euglenoids..

Reduce the nutrients: P:some of the extra flake feed is passing right through your fish: cut down amounts.
N: ammonia is being generated by the breakdown of organics in your filter (canister eh?): clean it more often.

Planktonic grazers: get a founder population of rotifers, copepods etc. from a friend with a clear heavily planted aquarium. Get a couple of gallons of mulm off the gravel and add the "dirt" to your tank.

Just what wetman said. ;)

Thanks For the advice!! I am using a Fluval 404 Canister Filter. Two 660 Power heads!! Undergravel Filter!! Water parameters are: Amonia 0, Nitrite 0, PH 7.5

You could also get a Vortex XL and use it. It will clear it out, but you need to 'fix' that prob too. The Vortex is an accessory type filter. I use it after water changes. It will make your water crystal clear..

I would recomend getting the Vortex Freedom Filter, alittle more expensive but it has some new stuff to it, a new valve, and it can run longer without clogging.

www.Bigalsonline.com is a great website for fish supplies.

Excellent product! I learned about it here on Aquaria Central. This Link (http://www.petsmart.com/fish/shopping/filtration%5Fequip%5F%5F%5F%5Facces%5F/other%5Ffiltration%5Fequipment/products/product%5F16187.shtml) should take you to PetSmart.com where I bought my Vortex XL. :)

Joe, was it you that posted the drastic before and after pics of green water in your tank? That is what sold me on getting a diatom filter. If it was you, they should give you a commission!
Could you repost those pics?

A UV sterilizer can take care of the green water quite quickly, too. The thing is preventing from reoccuring.

Am I the only one who hasn't mentioned the obvious? Your fish load. I'm no expert on JDs but isn't 8 really crowding such a tank? I also thought that a 55 gallon could hold only 1-2 JDs at max.

I believe your fish load is too high, thus causing a huge imbalance in your tank... especially in terms of nitrates (and ammonia if your biofiltration isn't good enough). Check the ammonia, nitrite and nitrate levels of your tank.
