how do i stop my fishtank from going green,it went green a week after i cleaned it?

Answer 1

I'm assuming you are talking green water, and green stuff on the sides of the tank. Green water is caused by an algae bloom in your water. This is generally the result of lots of plant nutrients, and light.

1)Clean your gravel with a gravel vaccum every week, and change 20-30% of your water.

2)Don't over feed food = nitrates, and algae like nitrates.

3)Watch your nitrate levels and keep them under 10 ppm.

4)Add plants to compete for iron, and phosphates.

5)Reduce light.

Answer 2

Depending on what kind of fish you have, the size of the tank, and where the tank is placed, algae can grow quite rapidly. For example goldfish are relatively dirty fish and will cause a lot of algae growth/green water. Also, the smaller the tank the more concentrated the algae growth, and if the tank gets a lot of sun it is easy for the algae to grow as well. Putting excess food in the tank can also cause extra algae growth.
Too fix it make sure your filter is clean, and if you do not have a filter, it would be a good idea to get one. Also, another option is putting snails in your tank, they are very efficient little algae cleaners. Keeping stones at the bottom also helps a little bit to catch some of the fish gunk, which contributes to algae growth. You just have to make sure to clean the stones every once and a while.
Hope this helps!

First of all do about a 50% water change, take out all you plastic plants, rocks, ornaments except for the live plants scrub them with a toothbrush and then soak them in one gallon water and two cap fulls of bleach for an hour. Wipe the glass inside, change your carbon and clint your filtering material. Vacum your gravel fill the aquarium and then use a product called ALGONE, rinse your rocks ornaments etc, and then dip them in a solution of water and clorine remover (the stuff you use when changing the water) put them in (MAKE SURE YOU RINSE VERY VERY VERY WELL) you will probably have to change the water a twice a week for a while, Make sure that your aquarium is not in direct sunlight, ALGAE LOVE SUN

Answer 4

Algae eaters will NOT eat green algae.

Make sure you preform weekly water changes of 10-20% of the tank water.

Keep it away from the windows and feed less.

If this does not work, consider changing to reverse osmosis water.

Answer 5

Change your food from flake to pellet, and feed them less. My fishbowl was doing this, and when I switched, the problem stopped.

Also, if you have "friendly fish," get a pleco. They eat algae.

Answer 6

do you have an algae eater? if you don't then get one. my parents have bought one and it keeps eating the algae, even though it looks like there is nothing there. as your algae eater grows bigger, the more it eats. So BIG ALGAE EATER + BIG APPETITE = CLEAN FISHTANK

Answer 7

Try cleaning it regularly.
