    Hi Folks: I've got a 32,000 gallon gunite pool. Just tried using the new Poolmath App and was surprised to see the amount of acid it is recommending that I add is vastly different than what the web says. I've always used the Website and have been pleased. My PH is current 8.4 (just opened...

    Hello: I just closed my pool for the second time ever (or rather I had my pool store close it.) It rained a lot the week after closing and now I see there is 1-2" of water in my skimmer basket. I worry this will freeze. Do I have to put anti-freeze in the skimmer? If so, is there a product...

    Do test kit chemicals go bad?

    Hi folks: Just curious if any of the drop chemicals in the test kits can go bad / expire? Mine are 2 years old (this is their second season) and they still work and change colors, etc, when expected. But the colors aren't as "vivid" as last year, etc. Thoughts? FYI I've got the TF Drop kit.

    It's Confirmed...I definitely have a leak in my Gunite pool :(

    Well, I did a bucket test last night on my 40 year old, 32000 gallon Gunite pool. And it failed. Water in bucket essentially didn't move. Water in pool went down about 1/2" and this was with the pump off. So I'm losing water with the pump not running. I've done some research and understand...

    Hi folks: Even though we are getting our 4th Nor'Easter in a month, spring is just around the corner. I'm hoping to invest in a pool cleaning robot this year to help keep dirt/debris off the bottom and reduce the amount of manual vacuuming I have to do. But I have no idea where to start. Can...
