Ascorbic treatment

[essikr]

Thanks for the advice szpiano , my test kit is a Taylor K-2006. I followed the directions they show . I have been using a 1"tablets in the chlorinator feeding after the filter and heater.I didn't know that they were stabalized and would raise the CYA. Are you suggesting using only liquid chlorine?

In the steps suggested I'm to add 69 oz of sequestor follow the directions to step 12 then add 69 more Oz of sequestor. I see no menthon of using the ascorbic acid to put the metal that is staining the pool back in solution? When I first did the ascorbic treatment the stains all disappeared. I assumed the metal was in solution and the sequestor would keep it there.Since it didn't , thought I didn't use enough sequestor.

I guess I was lucky for 18 years never having any problems like this!

They are definitely stabilized and are continuing to add cya to your pool. I didn't take the time this morning to go back and reread through this thread about your specifics except to find that you said your cya level was 120. Maybe somebody said it above as well and I just didn't see it, but NO MORE PUCKS for your pool. Szpiano is right about that. This is what happens to a lot of pools --- the owners continue to use pucks day after day, month after month all season long and unbeknowst to them, their cya level continues to rise. But, they don't use higher and higher chlorine levels to compensate for the higher cya level. Then, they can't figure out why they get algae because they have always had chlorine in their pool. Stick with bleach and you won't have that problem or rising cya.

I can testify as to what Watermom is saying. I fought algae all last year due to high CYA and I quit using pucks. I too fought the drain and refill solution even though we are on city water. I had to vacuum to waste so much that I eventually had the same result as if I had drained it all at once. This year I think I can get away with using pucks while we are away on vacation but I will go back to bleach when we return.

Good Luck
