I have to 200 socks and floss too been changing them every 4 days and I used a canister for 2 nights In a row with no help.

floss
 

what size sump and what is the turnover rate? powerheads in tank?
I don't see how filter floss wouldent remove the haze... must be pretty fine stuff. When you do a water change does the old water look cloudy in the bucket? does it settle after time.....

my sump is 75g
flow rate 7000 litres per hour
4 maxi jets
2 wave makers

When I do the water change the water seems cloudy too but hard to say because I always blow the live rocks with a turkey baster before water changes.

If your calcium was the issue and it was binding in the water column I'd have to think your pumps would all be seizing up due to calcification. I doubt its that. Could be an algae or bacteria bloom of some sort. Can you post a picture of the tank so we can see how cloudy it is?

I just added a UV yesterday will wait for a few days and hopefully that solves the problem. The picture of the tank is on the first page but it is hard to see exactly what I meant.

ah ya sorry, my work blocked the image.

Have you tried turning your gyres off for a few hours? Shut them both down and see if your tank clears, they can pull dust of the bottom with the gyre they create. Your coral will be fine for a while with them off.

Just an idea.

Tank looks killer btw...

Thanks for be advice guys. I will give it a try tonight.

Just an update bought a uv yesterday and when I got home today.. crystal clear!

uv
 

Awesome must be a bacterial thing. What size UV and how much flow? I'm currently trying to properly size a pump for my 18w aqua medic helix.. I'm thinking 300-400 LPH suction from skimmer chamber discharge into fuge....

have any pix how you plumbed?
