I have 0 nitrates, I’m running a fuge with cheato for 5hrs a day and now I’m wondering if I should turn off my Protein Skimmer??? The 75g tank has been running for 2-1/2 months with live rock- 4 clown fish, 1 yellow tank and a few clean up crew, and have a good amount of soft coral. Anythjng I have to worry about or just let it be?
