Green algae?

[Amys6621]

Can anyone help identify what is growing on my LR? I have a 32g biocube with 4 turbo snails, 2 clowns, 2 camel shrimp, and a coral beauty. I do 15% water changes weekly. All parameters okay except calcium is 480. Any suggestions on how to stop it?

I honestly can not tell what it is, but i know a more experienced aquarist will...but i will ask the question i know the experienced one will ask...What are your parameters? How is the flow in the tank? Your light schedule?

Does it come off the rocks easily with a brush? It's kind of hard to tell from that picture, but it almost looks like Cyanobacteria IMO. This does come in many different colors.

PH -8.0
NO2 -0
Ammonia -0
calcium -480
NO3 -0
PO4 -0
KH -143.2
Salinity -1.023
Temp -76 degrees

I have LED lighting that is on a timer for 12 hours per day. It cycles thru the sunrise, sunset, and moonlight settings during the 12 hours. I have run a protein skimmer and a filtration system that came along with the tank. everything I run came stock with the 32g biocube.

It does not come off easily at all. I tried to scrub a small portion and it wouldn't budge. It looks like green velvet in some places.

Hmm. The link below might help. (Green Turf Algae)

Also, I'm not sure what kind of a brush you used, but you might want to give a wire brush a try. Just make sure to scrub the rock in a separate container though.
