I'm having a diatom outbreak on my 10 months old tank. Tank is 180 gallon mainly sps. I'm running new silica buster on my rodi unit. I think it's triggered by those siporax I added to the sump a months ago. And dosing po4 and no3 made it worse. I removed the siporax 5 days ago and I haven't touch the tank ever since. Right now,It's coved in diatom. I'm thinking to let it grow and when those silica get to certain level it will die. Is it a ok to let it grow or I better clean it out?
