Need more information to make an educated guess.

What are your basic parameters? Amonia, Nitrite, Nitrate, PH, SG, Temp.?

How old is the tank?

Does the livestock "liven up" after the lights come on?

my params are all good this started to happen after i remover my canister filter and added a sump and a 250w MH

We need more specifics on parameters than "good" This is actually really important. Most likely it is something like diatoms if it is dust-like, but they usually increase while the lights are on and die back when they are off. Not the other way around.

ok well here are the parameters
nitrate 0
nitrite 0
amonia 0
PH 8.3
SG is 1.06
temp is 80 constantly
calcium is high over 520
phosphate 0
please help and I agree with the fact that its weird the dust disapears when the lights come on
