thats diatoms. do regular water changes 10% daily until it goes away. its there due to excess nutrients. do you have any fish? corals yet?
 
diatoms are a part of the cycle process.

Dont do daily water changes. That can disturb your bacterial cycle, especially on a new tank. Continue with water changes as normally scheduled.

Get some organisms that will eat diatom bloom. Most snails will, you just need to read up on which ones, as there are a few (like tongans) that are strict ditritevors.
 
thanks guys for putting a name on this so what am i doing wrong why did i get this and is snails the only way to remove it i have another ? when i do a water change and lets say a 10 % do i 10% of the tank water or tank and sump
 
Diatoms come with all new tanks. They're a part of the cycle. If you cycled right they should go away soon enough.
 
What are your parameters? Ammonia, nitrate, nitrite?

i do a 10% on total water volume

i have a 29gal tank with 15 gallon refugium. 10% is 4.4 gallons. i do 6 gallon water change every saturday.....alittle over 10% actually
