Whoa! If your chlorine level is high, do NOT use the polyquat. It's not compatible with chlorine that high! If you've already purchased it fine; keep it for a future need.

Also, don't put phosphonate in (HEDP); again it's not compatible with very high levels of chlorine.

Please post your POOL info -- surface type, gallons , pump/filter make/model, etc. -- in your signature (link in my blue signature block) AND please report a complete K-2006 test set. I particularly need to know what your CYA level is. (You don't have to repeat tests you've done recently -- just tell me what your current levels are)

Do be SURE to keep your pump running -- high chlorine will break down whatever you've used to lift the metals, but if it can break down in the filter, then the metals will end up there, and you can remove some from your pool when you clean the filter.

As far as I know, the CuLator *is* compatible with high chlorine, but I'll call this AM and ask.

However, NONE of these things will arrive in time for this weekend. If you have access to local citric acid -- I'm not clear on what you have been using; if you post EXACT product and brand name, and approximate product age, I should be able to tell -- and IF the citric acid lifts the stains, then with your very high chlorine, you can add it, put the metals in the water, let the chlorine break it down and *hopefully* it will be filtered out

BTW, if you are not doing so, with HIGH chlorine, be sure to use the SMALL sample size on the K-2006. If you fill to the 10ml line, each drop is 0.5 ppm chlorine, rather than 0.2
