Hey... before getting to my question, just wanted to say thanks, I post very infrequently because the experts contributing to this site answers nearly all my questions.
I've got well water with high metals and a small leak in the pool. There is an automatic pool leveler that adds water automatically. After about two weeks I the pool turns clear but with a green tint. To cure the tint I've been adding a product called pool magnet plus from Bioguard which seems to work well. This time I combined two quarts of the pool magnet with 2 pounds of powered sequestrant. (probably not good but....)
pool size is @ 40k gallons, gunnite,
On to my question...
Prior to adding the chemicals last night I had FC of 3.5, then I added the two quarts of pool magnet plus and 2lb of sequestrant (as per the directions for my size pool). I left the pool over night with pump off (therefore chlorine generator not running). In the morning I had 0 FC. Stabilizer at 80. Pool crystal clear and blue with no algae but just curious to know if there is any correlation with adding the chemicals. The label on the sequestrant suggests not shocking the pool so I'm waiting a week and holding my breath that I don't get an algae bloom. Note that I also tested the water coming off the chlorine generator directly and it isn't showing any difference in the FC levels, salt at 3k ppm. Perhaps the chemicals are giving me some false readings?
Let me know if you need any other test data and I'll update with exact values but total alkalinity and PH seem to be good.
