Answer 1

You can get snails that will eat the algae, or consider adding algae eating fish such as suckermouth catfish, siamese algae eater and mollies. When changing the water, you should only change about 20% of the water each day. Green algae is caused by too much disolved fish waste. You may consider getting a different kind of water cleaner, or a more powerful one.

Answer 2

Green water is an algae bloom and is harmless but unsightly. You don't need to use chemicals - chemicals really have no place in a fish tank - and you don't need to tear your tank down. Algae needs two things - light and nutrients. One effective method is to black out your tank for three days - turn off the lights in the hood, take a blanket or tarp or something like those black plastic garbage bags - and cover the tank - no light at all to get in. The fish don't need light and any plants will be fine for that time. You can feed the fish scantly during that time. You also want to do water changes - 20% - maybe two times a week or so until it clears up. Look at what you are feeding - most people overfeed. You don't usually need to get more fish (algae eaters) to clean up - especially with greenwater - they add to the bioload of you tank and a lot of time contribute to the problem instead of helping. Then you can get fine filter floss and add to you filter. This will help take anything in your water out of suspension.

Answer 3

Make sure you have proper filtration, is enough water being pumped through the filter every hour, make sure you have proper things in the filter like volcanic rocks to keep the bacteria thriving, when you clean the tank do not take all of the water out only about 1/4 of it, don't ever clean all of the sludge out of the gravel, you must leave some behind to keep some of the bacteria, make sure the tank isn't next to a window where sunlight is hitting it, the sunlight will surely grow algae.

Answer 4

is the tank in a lighted area, like near a window, or is it in an area that sees very little intense light.if it is in an area that gets lots of light, move it to a location in the house where there is very little light, change the water again, and keep the lights off unless your looking at your fish.that might help out alot.i keep mine in a hallway that has no windows, i close the bedroom doors so that a minimal amount of light is cast on the tank thruogh the day, and i keep the nitrites and nitrates down through the use of live plants and filtration; i have never had an algea problem.

Answer 5

Clean the tank regularly and go to the pet store and ask about snails or fish that help keep the algae growth down (there are fish that eat the algae).

Answer 6

turn off the light except for 1-2 hours at night

Answer 7

The best way is to move the tank to a place where it does not get direct light from the sun. This should solve the problem.

Answer 8

You can go to any department store that has pet supplies and buy a small bottle of algaecide. It should clear your tank up. Be very careful and do not put too much in, it can kill your fish.

Answer 9

take the fish and the water out....dry the inside and clean it well...put some wood shavings in the bottom....get a hampster...and have a fish fry

Answer 10

Get snails or another animal that feeds on algae.
