Can someone help me identify this stuff along my sand line? Is it
cyano? No
cyano is exhibiting itself on the top of the sand or anywhere in the tank. I'm sure I can get a lot of info about how to combat it in the recent thread if someone can just confirm that's what's happening, or if not, tell me what I'm up against. There are occasional small bubbles coming up from the sand, especially when crabs walk over it.
The tank is 100 gallons with filtration built in the back (bio balls, etc).
Nitrates 10,
nitrites 0, KH 200,
PH 8.4,
salinity 1.021. I do not have a
skimmer on the system - I was hoping to get away without one as the tank design would make the addition of a
skimmer awkward.
Thank you! -Deeder
