Hey guys, long time follower of the hobby and AQ Co-Op, but first time poster. I currently run a 10 gallon guppy fry grow out tank, small breeding for profit operation, but my water in said tank always seem to be green. I don't have any huge excess of algae on the tank wall, do 50% water changes weekly, and feed the Serra Micron food. I have tried and tried to get it back to clear, but to no avail. Any input?
