Algea problem?

FrostMan242

My tank is now a very dark green, I can't even see the fish anymore, is this because of my filter, or is it algea? Everytime I clean the tank, it stays clear for a day or two, but then goes back to dark green! Should I get a new filter, and how do I fix this?

Check your phosphate levels and drastically reduce your lighting periods. Cut back on feeding as well, you're only fueling the nutrients even more.

Good luck.

Also try changing the filter media a little more often (Like once a week or so) until it clears. I wouldn't leave the lights on for more than 4 hours until it clears up, then set them to go for 8-10 hours after it clears.
