Aquaponics Update

Last week we changed the water of our tank and scrubbed off the algae but now the tank has turned completely green again. The algae is also starting to come back so I think we need more plants but we already have like 7 plants and only 3 fish. I think the cause of tank turning green might be the fact that Brooklyn overfeeds the fish everyday, she doesn't want the fish to be emaciated and, every time she walks by apparently the fish look depressed and she feels guilty so she feeds them.
