Lights are separate am wondering where the po4 is coming from though. Using ro/di with a TDS of .0 feed ocean nutrition flake 1x daily-rince all my frozen foods. Why nothing in the DT?
Why nothing in the DT, I dunno. If your fish don't demand to eat frozen just stick to pellets/flake. Keep in mind anything the fish are eating be it high quality flake/pellets or rinsed frozen still has a ton of phosphates. At the base line of organisms they use ATP (adenisine triphosphate) for energy. So all foods have some, and those not used for energy/growth are still in the tank.
