So I'm having what I believe is a diatoms outbreak for the last couple of days, which I've read is completely normal in a newly cycled tank.. It's not on the glass at all (yet), mostly just covering the sandbed and the live rock. I was wondering if I should just do PWC and keep the lights off more than usual until it passes? This is diatoms right? Or something else?
