Ummm, Im embarressed to say...hehehe, Thats coralline coating the front of the glass... I have to admit I got really discouraged with the tank after the bad started to happen. Right now the only thing Im battling is red slime and coralline algaes. I figured the substrate in the current tank is just filled with organics helping to fuel it.
When I remove the rock for the transfer Im going to scrub and rinse them in two tubs of the current tank water then put them in the new tank with the remaining water then adding new water for topoff,kind of like a big water change. I know doing this is probably going to present its own problems but, Im hoping they will be easier than the red slime.
