    CYA Disappearing Act

    Well, my filter is overdue for cleaning, bacteria or not. Speaking of, has anyone isolated or discovered what bacteria (single or multiple) is eating up the CYA and causing it to vary so wildly? Bud

    CYA Disappearing Act

    Thank you for the replies. I had no idea that TFP had a wiki link. What a treasure trove of information. Great stuff on Ammonia. In regards to FC, it's holding steady now. It seems that once the bacteria (if that is indeed the problem) begin their end cycle, the FC recovers rather...

    CYA Disappearing Act

    I know this topic has been covered ad nauseam but I would like to relate the details of my CYA experience. Background: I have been at this pool chemistry game for five years. I'm certainly no expert but with the help of this forum, I have successfully managed my pool through five seasons with...

    Pool Math app does not recognize my paid subscription

    Well, I still cannot technically restore my subscription, and the app still shows the subscription as expired. All that aside, the app appears to work perfectly now. It records new logs as if the subscription is paid up. I'm happy that the reset on your end apparently works for now. Thanks...

    Pool Math app does not recognize my paid subscription

    Thanks for getting right back to me. So, I found the button but the response was "No Subscription Found". That page also indicates my subscription expiration date was today at 9:43am, but I've had this trouble for months now. I also received a notice not long ago stating that my subscription...

    Pool Math app does not recognize my paid subscription

    I don't quite understand where "Under the 'About TFP'" is actually located. I looked at and around the "About TFP" forum but all I could find were forum member posts, including this one. I spent a good amount of time looking the entire website over but to no avail. I'm sure the "button" you...

    I have a recently renewed subscription to pool math. However, every time I open the app and request a new log, the app pops up with a "premium subscription required" message. I then press the subscribe button followed by the restore subscription button. The next message says "no subscription...

    Jandy transformer voltages seem odd

    My Jandy Aqualink RS control board does not power up, i.e. no visible lights and no command functions. I reset the board, tripped the breakers to let the system rest, removed and replaced the lithium coin battery, all to no avail. I checked the secondary on the center-tapped transformer and...

    Acid drop Test?

    I am new to pools, having just put in a 35,000 gal in-ground pool with Pebble Fina finish. The contract comes with 30 days of free pool service so I am using a "pool guy" for now. They started the pool up with a "hot start", adding acid to the pool to mildly etch the plaster which allows the...

    Throwing used test chemicals into the pool

    Thanks for the quick reply. I have been tossing the test water in the dirt and I'll take your advice and continue to do so. Thanks also to everyone associated with the site. What an amazing wealth of valuable pool information!

    Throwing used test chemicals into the pool

    Total newbie question here. Is it safe to throw the chemicals used in the TL-100 test kit into the pool after testing? I can't imagine why it wouldn't be safe considering the dilution rate (35,000 gal pool), but I just wanted to get a warm and fuzzy from one of you "old heads". Thanks much...
