Can anybody identify this type of algae. Tank has been cycling for months now. Haven't seen a spike in ammonia, but then again I didn't have a test for about the first month. I have seen different stages of algae. Started off brown, then the brown turned into red or pick algae then that turned into this green algae. I was wondering if my tank is done cycling? Just tested the water today and ammonia, nitrite, and nitrate are all at 0 ppm. Also I do use Ro/Di water.

That's just green algae. Time to get some snails. Nice rock work!

Green Film Algae or possibly Cyanobacteria.

Cloak, I too am thinking it's possibly cyano

Unless you used tap water and have old pipes, you aren't gonna get an ammonia spike on it's own. You have to introduce it manually. Nitrate could be showing 0 since it could have all been taken up by the algae you have. If you never introduced ammonia manually, I would add it in before you put any live stock in the tank. Easiest way is ammonia from the hardware store. Dose it up to 2ppm, and check 24 hours later. If ammonia shows 0 then you are good to go.

Since you have no livestock in your tank. Try sucking as much of it out as you can, then shut your lights off for three days.

To get ammonia to read, go buy pure ammonia from the store. Slowing add some in your tank, test it and keep adding till you reach 1ppm... Wait a day and test. If ammonia is gone your tank is turning ammonia into nitrite.

Then you test for nitrite and if you have zero after your ammonia has gone from 1 to 0 in just a day. Your tank is cucled!
