White flakes in water

[saltwaterbob]

I have a 180gallon fish only tank. The sump has a huge 40 gallon sump with bio balls and a monster skimmer. The white flake are not in the sump but visable in the display tank. The pump is 1200 gph to a dual overflow. I have alot of water flow crashing down onto my filter pad. The fine white pad clogs in 2 days. Can the white material flakes come from the crush argronite which is 5 years old? The weird thing is that the white flakes are only in the display tank so I do not think they are be knocked off the filter material used to trap the particles. Would a Magnum work? or what about a ocean clear 340?

More than likely they are just calcium and/or other mineral deposits that have broken loose from your decorations, coral substrate, mechanical filtration units (i.e.) filter tubing, powerheads, heater, etc.

I just teed off the 2 1" returns to go thur a 16" white 100 micron sock. Will see if that helps catch everything floating.
