pict of sand

And yep, thats Cyano :-/ check your mag, O2 (add an airstone for safety and extra O2), check nitrates and ammonia

 

is it cyno or coraline

 

this pc sucks my nitrite and amm r at 0

 

isnt there chems to take care of it

 

so if i bring my mag levels up that should get rid of it

 

No chem's needed, more flow is the best way to remove it.

 

i tryed to turn the flow up but the littlest ajustment and the sand starts blown around

 

Try aiming your powerheads towards the surface slightly.

 

If all else fails ( increased water movement, water parameters normal, cut down on feeding etc) I have used ULTRA LIFE RED SLIME Remover and I had great success and other people on the site have had the same success it really works and I have not seen any red junk in my tank since I treated it . Don't forget it is not an algae it is a bacteria. That product did not harm any corals ,fish, inverts, etc in my tank by the way.

 

I raised my mag, O2, and flow. That got rid of it, quick too
