New pool, first test results!

Jump to latest Follow Reply
Congrats on the new pool! Being vinyl there are no concerns for a low CH. You do need a minimum CYA of 30 though, so make sure to add some stabilizer. For now, keep the FC between 2-3 ppm, and once you add the stabilizer, balance the FC as noted on the [FC/CYA][/FC/CYA]. The rest looks pretty good. I wouldn't let the TA get any lower than 50 though, and with a heater, make sure the pH never drops below 7.2 either. If you stick close to the TFP Recommended Levels (link below) you'll be fine.

Adding CYA:
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.

CYA Testing:
Proper lighting is critical for the CYA test, so you want to test for CYA outside on a bright sunny day. Taylor recommends standing outside with your back to the sun and the view tube in the shade of your body. Use the mixing bottle to combine/gently mix the required amounts of pool water and R-0013 reagent, let sit for 30 seconds, then gently mix again. Then, while holding the skinny tube with the black dot at waist level, begin squirting the mixed solution into the skinny tube. Watch the black dot until it completely disappears. If it helps, pour a little, look away, then look back and pour some more. Once it disappears, record the CYA reading. After the first test, you can pour the mixed solution from the skinny view tube back to the mixing bottle, shake, and do the same test a second, third, or fourth time to instill consistency in your technique, become more comfortable with the testing, and validate the CYA reading. If you are still questioning your own results, have a friend or two do the same test 2-3 times. Share your results only after everyone is done to see if you came up with the same average results.

Thank you Cliff. Really trying to enjoy as pool as much as possible. Scheduled closing second week of October. Since I got a cover through PB they will close pool for us. Kinda don’t feel comfortable then adding their chemicals. Gotta research the opening and closing section.
 
Looking good for new water. Add a bit of CYA and keep your FC up. That water will be fine to start next season with.
