Green cyano or bubble algae?

[mattrob]

Hi everyone,

I am really struggling with this one, last week I took out every rock and cleaned with a toothbrush and siphoned the sand. And not 1 week later it's covered every inch again. Am I looking at bubble algae or green cyano?

About my tank,
3 months old
3ft 270l dd aqua pro reef 900
6 fish, 2 tuxedo urchins, 3 conches, 6 snails, various coral frags
Ammonia 0
Nitrite 0
Nitrate 10
Phosphate 0.1

Any help is greatly appreciated as it's starting to kill corals

Cyano. Bubble algae is hard ( imagine a bunch of tiny grapes)
Looks like cyano coated oxygen bubbles

Thanks guys, just assumed bubble algae based on some obviously misdiagnosed photos online.

I would suggest you use a small hose and suck off as much as you can from the rocks then take a turkey baster to blow off all of your rock, while you do a 20-30% water change. Make sure your source water is RODI. Then I would use chemiclean (follow the instructions) and see if that gets it to go away.

of just get a sea hare and return once he eats everything

Looks to me like standard algae as the periphyton is forming, and the algae is either making oxygen bubbles or there some some micro bubbles swirling around that stuck to the algae.

Hi all, it took 2 doses of chemi clean but it is now gone to be replaced with hair algae that hopefully my 2 tuxedo's will make short work of. Thanks everyone
