Nuisance algae or good?

[Jonesyg]

Hi all, I have had a slow growth of green algae across my live rock, any ideas to what it is and if any fish/ cleanup crew would eat it? I currently have a peppermint shrimp, cleaner shrimp, lawnmower blenny and a few turbo snails. Water levels are stable with no recent fluctuations. Thanks in advance!

That’s green Cyanobacteria, try and syphon it out.

You will want to find out why that popped up in your tank, most likely a high nutrient issue. Siphoning is a good idea but it will come back until you figure out the source of the problem.

It was present on the live rock when i received it from a running tank in a small quantity, I didn't remove it which i wish i now had. I do weekly water changes 10% and change filter floss, running a phosphate and carbon filter with a skimmer, no sump.

What are your nitrates and phosphates?

What are your nitrates and phosphates?

Nitrates are at 0, I have ran out of phosphate tests so waiting for some to arrive so not sure on phosphate currently
