dory Posted September 20, 2004 Share Posted September 20, 2004 hi all, today i noticed a strange green film on the surface of my tank. It looks like algae is growing on the water surface, is this possible? I stir it up but after a while it just re groups, it wont go away and i dont know hwat to do. Any suggestions??

BlakeyBoyR Posted September 20, 2004 Share Posted September 20, 2004 It COULD be algae or alternatively it could be protein build-up from fish waste and food etc. Can you get a picture of it at all? Link to comment Share on other sites More sharing options...

CThompson Posted September 20, 2004 Share Posted September 20, 2004 I will assume that what you have is algae. I have some 200l barrels outside where I grow live food for my fish, and persistently I have a floating (completely on the surface and not just below it) bright green algae. I find it only likes still water, if I spray it with a hose every day, it will go away (only to come back later), or if we have a few days of rain (it does happen) it will also go. If what we are talking about is the same stuff, my guess would be that if you have it in a tank situation, you may not have any aeration. Following, my first suggestion would be to add an air stone. Or if you have a spray bar , place it above water level, to cause it to splash accross the surface. Another suggestion would be using an Ehime Surface Suction Extractor, provided you filter via a canister filter, this will skim your water’s surface, and should clean off your algae. What you also can do is try and work out why you are getting this algae? Algae is usually caused by an imbalace, and that doesn’t just mean too much light, as it can also mean not only too little light, but a host of other things that are occurring out of balance. But to simplify things, if it is an alga, not knowing what other plants you have in the tank, you could turn off the lights for 2-4 weeks, and this should get rid of the algae. The problem here will be if whatever imbalance is in your tank, once you turn your lights back on, the imbalance will still be there, and the algae may come back again.
