Algae on the SB?

NanaReefer · Jul 27, 2014

Tank is 9wks old. Arag-Live Figi Pink sand. Diatoms came and went. In it's place are lil tufts of green algae all over the SB. Not on the rock, glass or anywhere else. It actually glues the sand together. It's almost carpet like when I move the sand about.
N02/N03=.0
Ammonia=.0
P04=0.05

Could it be my LED's that is causing this?

What kind of salt do you use? I read in another forum where some reefers thought it was their Seachem Reef Salt causing it. I think it could be cyano.

I'm using Reef Crystals and have been for 5yrs. I'm actually seeing lil tufts of of green algae. Nothing of the normal looking cyano.

Cyano can be blue-green from what I read. I get some of the same stuff from time to time; that's when I cut back a little on the feedings.

I don't think this is cyano. It is green fuzzy tufts. I just cut my lights down by 2hrs. Anyone else with suggestions?!!

can you post a picture nana?

It's very hard to do with LED's

I just did a water change, vacuuming the sands surface trying to remove as much of this crap as possible. Dumping it out the water was actually tinted green. It is no where else but on the SB.
Do you think maybe it was/is the live sand I used? Even my son commented, mom you never had this before.
I've been dosing SeaChem zoo and phytoplankton 1xweekly at half a cap full. Think I'll stop.

gosh, I don't know, it sounds unique. I might stop the dosing also

It has to be from excess nutrients causing this nuisance algae. I would recommend to quit dosing and when you start back dose less and try to figure out which one is causing this issue. I have found that most liquid additives such as coral foods etc. will cause problems If dosed too much. When I dose I only use half the recommended dosage.
