Why is my tank a giant green cloud?

[Jerinanyon]

Try not feeding them any pellets for a few days it hoppened to me and looked terrible. Just stopped using pellets for a few days and did some water changes. I use the same as you and it worked for me

Update:

Tank is crystal clear after using the lights less for a few weeks. Ordered the green killing machine also to ensure I have no issues later on, therefore I could leave the lights on an hour or two longer if I wanted to. Thanks for the help guys, the advice worked.
