New Tank algae

[esteem]

Hi

I setup my tank everything is up and running lighting up fish are in tank has cycled at least.. now what am i 2 expect in ways of algae? I use RO water and have lighting on 11 hours a day. I've noticed my rocks and a little of my live sand is a little brown. Question is how brown will it get? hehe and what type of algae is it? and what 2 do about it?
Thanks
Ter

-Diatoms are single celled algae, brownish in color. It starts out as a dusting on the substrate that rapidly turns into a mat that can cover the tank over in just 5 days, provided that they have a surplus on nutrients available.

The cause: excess nutrients, silicate and silicic acid are the ingredients for a diatom bloom. Silicic acid enters the aquarium by using tap water; substrate can contain silicates that leach out over time. RO/DI units can filter silicic acid out, but only for a limited time. Eliminating silicates can control diatoms.

i use tap water, so i guess, until i get a RO unit, i'll be dealing with this somewhat.
meanwhile i have sand sifter stars, lawnmower blenny, and snails, hermits.....algae "wrecking crew".
