The problem is that if I run activated carbon I strip the water to clean. The no3 is hovering at .5 and po4 is at 0.02ppm. Im already feeding 7 times a day and can’t get the numbers up. The skimmer has been off for 3 months and the fuge only runs 3 hours a night. Even feeding this much I can go a week and a half before I get algae on the glass. By using activated carbon I’ll strip the water even cleaner. I’m already loosing sps do to lack of nutrients. I don’t want to make it worse.
Even the ICP shows that the po4 levels are below recommend levels.
Eheim is set and runs 4 times a day.
Feeding 30ml of coral/fish food 3 times a day.
It auto feeds off the dōs
All this feeding and the tank is super clean
