You've got cyanobacteria. Darn tough thing to eradicate.

It is harmful! Will overgrow corals and fix nitrogen. Not to mention butt ugly. Nothing really eats them.

Increase nutrient export, reduce feeding, increase alk and pH, if using MH replacing old bulb might help.

I've fought them twice before and got rid of all visible cyano. Some will still be in the sandbed, but that's normal. Do a search and you will come up with the method I've used.

Thanks Tanzy..

Export nutrients by (1) Macro algae

(2) Protein skimmer

I am too fighting these buggers... Reducing the duration of lighting also seems to help

Is brown algae = diatoms?

Cos diatoms are caused by: (1) Indequate lightings

(2) High SILICA in water colume

Read abt this from this mth advance aquarist

Silica in Marin tanks
