    natural chemistry cya

    This product was recommended to me at a local pool store recently and I was wondering if there were any comments on it. The main benefit of this specific product was that it apparently raises your CYA right away as opposed to waiting the 4-7 days.

    It is the monosodium salt of cyanuric acid. It is extremely fast dissolving. From what I know of it the only drawback is the price.

    Thanks...it was a couple of weeks ago now that I looked at it...from what I remember it didn't seem to be outrageously priced in comparison to other CYAs. Ofcourse...now I'm curious enough to have to go and confirm that.

    One gallon of the stuff is supposed to raise CYA 40 ppm in 10k of water and costs about $25, it takes less than 4 lbs of CYA to do the same and you can buy 4 pounds of CYA as low as $9.95 on the net. In pool stores in my area 4 lbs of CYA go for about $16 and I've seen it for $10 on sale.

    Also, to raise 40 ppm CYA in 10k of water would take 6.6 pounds of Dichlor (dihydrate) which costs $2.60 per pound at Leslie's so that would be $17.16 and you would get 43.8 ppm Free Chlorine in addition to CYA and Dichlor quickly dissolves. So though you wouldn't add it all in one shot, you could add it as your daily source of chlorine for a while and be relatively economical.

    Ironically, the use of Dichlor (after taking into account chlorine usage) is actually more acidic than adding the equivalent amount of Cyanuric Acid from pure CYA.
