I am just sick and tired of dealing with this Fluval tank. I have tried every mod with this tank so I recently removed the AIO from my tank. For the moment I am using a Tidal 55 to filter my tank. There’s now is no more surface scum, and the water is clearer too. I have also gained a lot more room for more corals. Right now the tank is cloudy from stirring up the sand. I will be posting more pictures in the up coming days.
