1st test results - CYA down to ZERO?

[aylad]

Don't worry about the discussion above between waterbear and Ben, they're making it sound a whole lot more complicated than it really is. Just keep it simple: Yes, you need to add some CYA, either in the skimmer or in a sock or stocking in front of your return, and remember not to retest or backwash for a week or so because it takes a long time to dissolve and show up. How much you need to add will depend on your SWG instructions. And yes, keep adding bleach until you get your chlorine under control. As far as pH goes, if you're between 7.0 and 8.0, you're basically okay--the general consensus is that the lower you are on that end of the scale, the more effective your chlorine will be.......but then again, my pool "likes" a high pH so I don't try to fight it.

Hope this helps!

Question about CYA: Where does one get it and what are some product names? While waiting for a better test kit to arrive, my test strips indicate my cya is zero. Thks.

You may be able to find CYA at Walmart, Lowe's or Home Depot. If not, you'll have to get it from a pool store. Sometimes it is called stabilizer or conditioner. If the ingredient label says cyanuric acid or isocyanuric acid, it is the right thing.

First, where to find CYA: I got it at Lowes in MD, the Home Despots in the area didn't have much in the way of chemicals in stock yet. (I'll have to talk to my HD manager friend about that) approx. $10/3 lb.

Second: Tested tonight CYA up to 23. should I add some more to get in the 30-50 range? Other numbers FC/TC 2, CC 0, pH 7.8, Alk 150, Cal 350, Temp 81

Have a SWG 26,000 USG pool here in Katy (West Houston) Texas.

Just went to local Pool Warehouse on Mason and got water tested again an CYA is still low at 30 ppm and that's after adding 2 4.5 lb jugs !

So bought another jug for USD16.99+tax and will re-test after 2 weeks. You can also buy via web companies. I've looked and never seen in WalMart or Home Depot.

Walmart sells it as HTH Conditioner (almost drove my wife crazy trying to find it). Home Depot and Lowes both sell it around here. Williams Lumber sells it and has the cheapest price by far.

Does CYA degrade? Seems like a good "end of summer sale" purchase at the hardware store if it will store through the winter.

Not in the jar but it CAN be degraded in a closed pool under the right conditions by anerobic bacteria. (The phenomenom of closing a pool with a decent CYA level and opening it to find that there is little or none left)
