New tank syndrome in an addition?

[reefermadness]

I agree with 99.99% of what you are saying. I will say that if you have lots of hair algae you probably have a nutrient problem but to get a tuff here or there is possible with-out a nutrient problem.

Also I don't think diatoms is the only algae I see in the frag tanks I have set up. Right now I'm battling diatom, cyano (many consider it an algae but I know its a bacteria) cotton candy algae and some algae that is almost like a green hair but thicker and shorter. This tank is just about a month or so old tied into my system. I had a smaller frag tank previously and went through the same thing for months.
