My question is, qhen will algae come? there isnts any in there, or about, i thought it would come faster
Depends on a lot of things and what algae you are talking about. The lighting, food, and tank parameters all play important roles.
It is different for every tank but, overall, diatoms will come first followed by hair and then coralline. It may take two months for the entire algae cycle to complete with diatoms taking about 2-3 weeks to show up.
I have had my tank up for just over 2 months now and am still having diatom problems. They have died down a little, but I still see brown diatoms on the glass right now. I have not had any hair algae yet coralline is really starting to grow instead.
Figure that out...
