Hi Ralph,

The brown stuff that coats your glass, sand, gravel, rocks is a form of brown algae, called diatoms. They're fueled by silicates from tap water combined with your lighting. You won't get this problem if you use RO/DI water for making up your SW.

To control it now, you can use a variety of biological means, like sea cucumbers, algae blenny (fish), bristletooth (fish), various snails like the Astrea, Turbo and Trochus species. All of these will the diatoms for you.

I have a Eheim filter , why doesn't it filter it out, what kind of filter substrate do you recommand? I have circulary ceramic and a layer of (what looks like chunks of white sea coral), also a layer or little stones that look like their from a creek, but way smaller. What am I doing wrong so that so much brown stuff sticks to my aqurium and will the use of a Protein skimmer reduce this hazzard??

Thank you for now , I'll be back
