Not a new reefer but new to this problem. I have 120g that I had down for a few years back up and going now. It has been cycling for almost a month, everything was normal. Then I changed my lights out from 250W HQI, to 25OW with Lumenbright reflectors. As soon as I changed Diatoms exploded totally covering the glass and rocks.
Question is, should I just let it be and run it's course then vaccum off as much as I can when it's done, or should I try to keep siphoning it off the rocks, etc? There is nothing in the tank except Rock, Which was all dry from when my tank was up previously.
