GREEN ALGAE??????

[clowntri66a]

I know this doesnt belong in the aggressive section , but i feel comforetable with your guys opinions.I have green algae growing all over my live rock, i was just wondering whether this a good thing or a bad thing?Also if it spreads wildly what can i do to control it?I have a 75 gallon with a wet dry and a mtc protein skimmer and a power head 802 with a filter attachment.

What kind of algea are you referring to? Is it like a velvet sheet on the rocks or are you referring it to Calerpa algea which looks like plants? With that info I can help agood deal because I have dealt with it in the past.

i believe that this sign of algae means you have good water quality but two much light/sunlight/phospates. how long do you keep your tank lights on during the day, is it near a window? do you use tap water for evaporated water replacments? what fish do you have in the tank?

I agree about the lighting. It can make alge grow quickly if your lights are on too much or if you are near natural light. I used to have serious buildup until I turned my lights off in the tank. Now I have them on about 6-7 hours a day which has helped immensely.

Well lion fish its more like a vcelvet coating on the LR that has spread somewhat to the sand< and yes i do use tap water to replace the evaporated water,as far as fish go i have to lil huma humas a niger and some damsels.

Your algea is quite common but is not a welcome site in many peoples tanks. It is a diatom algea called Cyanobacteria. Nothing harmful to the fish but it spreads like wildfire and can make your tank look like crap. Cut back on lighting time. If you leave highpower lighting on a tank for too long it can cause serious algea blooms. If it is by a window get some shades.It could also mean high phosphates so do a phosphates test and come back with the results.

one thing lionfish left out, is maybe to try water with less phosphates/silicates in it than tap water like RO or RO/DI water.
