Just some healthy paranoia, but wanted to get some opinions. Tank came online on Feb 2nd, cycled in 3.5 weeks, had a small diatom growth about a week and half ago, then it all disappeared. Set up a QT tank using water from the DT and did my first water change as a result. Next day, this... It's growing so fast I can see changes in spread by the hour. I'm cleaning the glass daily and started running the skimmer. All normal, or should I worry? Have 4 Hermits and 4 snails. They are certainly not keeping up. There is a lot of green on the rock and glass. The sand is predominately the diatom brown.
