I just got Bens test kit last week and did my first CYA test this spring.

ZERO !!!

and I've just put in an Autopilot that you are supposed to run with very high CYA.

The JUG I got was made by SUN also said to disolve in warm water. Not being fond of that idea I poured it into the skimmer ... with a skimmer sock in place.

Two pounds were disolved and gone in 1 hour flat. Tested and I had 25 PPM according to Ben's kit. Next morning I repeated ... again disolved in and hour.

Done deal.

Soon the pool stores will have the liquid CYA and all this waiting a week, justified or not, will be history.
