It is all fine. It is most likely diatoms and just part of the cycle. Although can be due to high phosphate's as we'll.
Do you use ro water or tap water.
Otherwise it means your tank is doing what it should be.

it shouldn't however if it's brown slime on your corals you have another problem.

I think this tank is doing it's initial cycle as discovered in this thread:

Yes your corals and fish could be in peril if your tank is cycling.

using tap water. priming it and letting it sit.

should i be using ro water? will it make a difference if I start using r/o water now.
