Lemme restate, i just reread that.Thread says closed, you post open.
Not sure what you are saying your torch is doing.
Zero nitrates and/or phosphate is not good at all, stuff will starve.
Ive tried feeding more and whatnot and even turning protein skimmer off but nothing increase nitrates atleast. I looked at nitrates doses but they always say should be used by "experienced reefers". So im not trying to mess with anything.Not unusual for any coral to stay retracted for days/weeks before getting settled and opening. It takes time for it to adjust its processes after changing environmental conditions such as water chemistry and light.
Certainly opening is a good thing. We would want it to stay open during light hours and contract when dark, daily, every day.
You must maintain trace nitrate and phosphate in your water chemistry to feed not only corals, but everybody else living in your system.
Zero nutrients will in time, lead to dead corals and pest type algaes and bacteria.
