Algae Id?
Hey so not sure if this is algae or some other thing...
It kinda looks like brown sand and it grows on my rocks and sand and glass and there is alot more if it in the areas Of The tanks with less flow.....any ideas what it is? I originally assumed it was diatoms but after looking at some pics on google I'm starting to think it's not. Nitrate 1ppm phosphate 0.02ppm and tank is 11months old.
