Is there always an algae bloom in a new tank. I had 1 rock turn a little brown and 1 a little green and some film on the glass. I checked my phosphate and it was way high between .25 and .5. So I started my phosban reactor and now am at 0. Also since turning it on it appears I am starving my cuc. So my question is. Will some algae start to grow? My chaeto in the fuge isn't growing but it's not looking fragile either. My tank has only been up for 2 weeks. So I'm sure it takes time for a tank to not look sterile but am curious if diatoms will happen for sure.
