Dinoflagellates or Green Cyano Algae?
I have had my tank up and running for about five weeks now, in the last two weeks I have had an outbreak which looks to be dino or green cyano. The tank is 29 gallons with a ten gallon sump, two inch sandbed and 20lbs of live rock. I have been using ro/di water but I don't have a tds meter to know for sure that its really at 0. Two powerheads and my sump return make for 700-800 gallons per hour turn-over. I have had my lights off (150w MH) for the last 36hrs which helped slow the growth but that's about all. I don't have any fish so no feeding, just have some snails and two hermit crabs, one small green star polyp frag and one small zoa frag. The algae is mostly covering the rocks, yesterday I took out the rock and scrubbed it down with a soft brush in a bucket to get most of it off, I know this won't solve the problem but trying to keep it from completely taking over. The algae is green with bubbles that are sometimes attached to longer strings of algae going towards the surface. I have attached a few pics, I know they are a little tough to see. Below are the reading I have have from my limited number of test kits.
Ammonia: 0 Nitrates: 0 Nitrates: 0 Ph: 8.0-8.2 (Hard to tell with liquid test kit). Salinity: 1.024 Temp: 78 Thanks for the help everyone. |

One more thing to add, this algae (or whatever it is) is a bright green color. Most of the pictures I have seen of dino outbreaks seems to be more brown or red. If anyone has anything to add it would be much appreciated.

It's impossible to tell without a microscope, IMO. It could be either.
