To increase CYA via granular stabilizer, place the required amount as calculated by the Poolmath calculator into a white sock and place in the poolside skimmer basket. For those concerned about suction flow to the pump, suspending the sock near a return jet or from a floating device will also suffice. Best never to allow undissolved granules to rest directly against the pool surface. Squeeze the sock periodically to help it dissipate. Once dissolved, consider your CYA adjusted to that programmed (target) level. CYA test readings should show a rise in 24-48 hours, however some pools may experience a longer delay to fully register. Best to confirm final CYA in about 5-7 days before adding any more stabilizer/conditioner.
Thank you for the reply neighborWelcome to TFP! Glad to see you have a good test kit as well. For your tests:
- FC makes sense, but I suspect you had an error on the CC reading right afterwards. You might want to double-check your combined chlorine method and/or the reagent you were using. It's easy to get them confused.
- pH great.
- TA elevated for sure, but that can be worked a bit later.
- CH is good, especially for your area
- CYA ... definitely get a sock soaking to dissolve the granular stabilizer. You want a minimum CYA of 30, so use the Poolmath app to figure out how much stabilizer to place in a sock.
- Very important ... update your signature with all of your pool and equipment info. That will help us determine more about what levels are important to you.
Great to have you with us.
Thank you mknauss
Post pics of your equipment and valves. Could be a valve closed. Could be a cleaner line. Could just be low flow that you can't really feel.Return jet question
So the contractor winterized new pool.
I haven’t heard back , so I’ve opened it up myself
There are 4 ports at the same elevation
2 on one wall
1 on opposing wall
1 on shallow end wall
3 of them have flow , 1 does not
I’ve capped others systematically and nothing still from the one
Could it be for something else ?
Lucky to catch it , small 1/2 black blew off and was flooding yardReally need to see a pic of plumbing and valve to understand and comment.
