Green water?

[senorkevin]

A few weeks ago my water was always green. After 50% WC it was ok for a day then green again.
I decided to do a full clean (bleach gravel, clean glass etc). It was great for a week but now the water is green again. Also I am getting some slime in the filters
Any ideas what my problem could be?

What size tank? Stock? Water change schedule? Filter type? Water parameters? Lighting schedule? Planted or not? Sorry to throw so many questions at you but we need to know more before we can make suggestions.

Usually, it's too much light coupled with too many nutrients. Try cutting back on the light hours and reduce feeding amount ( or increase filtration & cleaning schedule).

Hope this helps

Maybe it is the sunlight. It is in a light area of the room but no direct sunlight

Are the levels ok?

Lowering your Nitrates through water changes will help take away some of the food for the algae but typically you have too much light if you are getting green water. If you black the tank out for a week or two it will get rid of it but it will just come back if you don't lower the light levels.

Re. my other post: The nitrates are the nutrients, the sunlight is the light. You should find a way to shade the tank from the outside light and lower the nitrates and you should be good to go!
