cloudy water

[roblarss]

I have a 120gal display tank with about 60 gal of sump. My doser went a bit crazy and I now have very cloudy water. Looks like watery milk. Doser is offline for about 7 days now and I have done 3 x 40gal water changes and its not getting any better.

It looks like a fair bit of mag and alk was added.

My Alk numbers were at 220ppm (12dkh) and after the first water change it dropped to 210 (11.7dkh). Last water change it dropped to about 202ppm (11.4dkh).

I am out of mag and cal tests currently.

Tested PH last night and got 7.61

It doesnt look like the fish are having any issues except getting lost in the tank. I can only see them if they get within 4 inchs of the glass. The zoas i can see are open.

The reading I have been doing says to not bother testing anyways as they will be false high reading from precipitate. The skimmer just makes a huge head of foam after a few hours and pops the lid off. The glass gets a slimy white film.

Any thing more that can be done or just ride it out as I have read on many articles.
