Is it crusty or gel like? I have a dark red coraline as well as the

deal with phosphates and nitrates.

I'm kind of new at having a reef tank. It is a 75 gallon with a tide
pool filter and I have a skimer as well. I have had this set up for
over a year now and things are good but I get a lot of red brown algae
all over the coral.I think it is stoping the growth of other plant
life.Is there something that can be done.
