Tried putting this on the build thread received no reply's will try again. I don't see anything in my new tank that I was not expecting except the green algae on the rock that has bubbles on it. However any advice as to what is there and if I should take action now I would like to know BRS said just to let it go I don't know. This is brand new cycled fishless with lights off. Have lights on now for 3 weeks lots going on. I cannot siphon
the substrate as the sand is lighter than the algae
