I’m not sure what else to do for my new tank. I used RODI water tested at 000. Rinsed sand with RODI, used fully cured live gulf rock. I have 4 med snails and a few astreas leaving me with a level of .4 nitrates ATM. What I don’t understand is how a tank that has only seen two puffs of coral feast I gave my cup corals, in which 95% of it was taken in by the tentacles can have a phosphate level of .19 . I added a bag of chemipure blue a few days ago and haven’t really noticed a difference in hair algae, What is my setup missing? I’m running a nano skimmer and I even have a desktop UV I got today as well.tanks been running about 3 weeks
