I added a pound or so of cal hypo to a 10k pool yesterday as chlorine was at 1 and ch was at 270. I got a message today asking what I did as the pool was slightly cloudy and there was a slight green tint in the pool

Cal-hypo always creates some cloudiness. High CSI increases the cloudiness. The green is likely to be iron.

If there's a cartridge filter, check the cartridge for iron staining.

Check the CSI and look for iron stains anywhere.

In my opinion, cal-hypo is not worth using, ever.

He filled the spillway (infinity edge pool) a week or so ago. It was low but I don't know if he used the city water or the well water.

I will take a look at the cartridge next week. It's actually a three week old jacuzzi filter but I'm betting it's not a pleatco in there. I think I should be able to pick up some test strips for metal at the pool store, but what to do if it does test positive for metal. Should I just leave it alone. I've never used sequestrants before.
