Algae Identification

[Donny Dutch]

I need help identifying some algae, photos are attached. Nitrates are near zerp, do not have the means to test phosphates at the moment. I used tap water initially but am using RODI now, I have done 4 12.5% water changes with RODI so far.

 

- 32 gallon biocube

- protein skimmer, heater at 78

- 2 months old

- about 20 lbs of live rock

- one yellowtail damselfish

- 4 snails, 8 hermit crabs

Looks like Cyano... comes in all colors.

Hard to tell 100% but appears to be cyano

Thought I would get email notified of comments, just saw these now.

 

I have a feeling it was cyano, I guess I’ll jus have to continue the water changes until it dissipates.

Cyano often pops up in low flow areas where detritus collects. Manually remove what you can (pulling a small fish net through the area usually works pretty well but it looks like you have crushed coral for a substrate, so it may not, and the large pieces may be trapping gunge, causing the issue), and increase the flow. Also, try vacuuming the substrate to clean it a bit.
