    How cold of water will you swim in?

    Last year, I took a swim at 60- degrees before I closed. I have to admit that even the 70s are not much fun. This year I won't be doing a pre-close swim. Our pool is already at 53 degrees and I'm keeping it open for a sulfamic acid copper stain process in progress. I only had two weeks above 65...

    Will a Circupool Core35 remember its settings when powered from a timer (120V)?

    Great and thanks for your reply, ajw22! I'm very much looking forward to powering it up next season and nearly eliminating the need for the bleach brigade. I ordered it late yesterday and Discount Salt Pool had already shipped it out this AM.

    Will a Circupool Core35 remember its settings when powered from a timer (120V)?

    I have a "plug and play" Core35 SWG coming from Discount Salt Pool. If I follow various TFP forum members' "fail safe" recommendations and plug it into a 120V timer that only powers-up the Core35 during periods when my pump timer runs the pump, will the Core35 remember its settings? I assume...

    Free Chlorine Removes Copper Stains?

    Thanks for reading and reviewing the article, JamesW. Interesting! :) Yup. Thanks! Guess I got the answer to my question about just adding sulfuric acid instead of implementing the (bogus) reactions.

    Free Chlorine Removes Copper Stains?

    Obviously it does not do so alone but, according to page three of this very interesting article, chlorine is the essential other half of the sulfamic acid stain treatment equation: Differentiating stains and determining treatment According to equation (2) quoted from the article above, FC is...

    Trouble with Stains

    The problem with winter treatment (or even early fall around here) is the Jack's #2 treatment instructions say 65F minimum water temperature!

    Spa Borate "Aeromatherepy" Stings Eyes?

    Sorry to throw you off, JamesW. I was just joking about "aromatherapy." Years ago, spas were sold with extra features to put aromas into the jet airflow. I don't even know if they are available anymore. What I'm experiencing is definitely not positive therapy and I"m trying to get to the bottom...

    Spa Borate "Aeromatherepy" Stings Eyes?

    I'll try that, JoyfulNoise. Maybe the FC is bothering me in my old age. The last time I had a spa I was in my late 20s and I don't recall this problem.

    Spa Borate "Aeromatherepy" Stings Eyes?

    My spa tests 30 ppm for borate and my pool tests 50 ppm. Both pool and spa run around pH= 7.3, CYA=30, FC=3-5, and CC always under 0.5 ppm. I run my CA and TA lower in the spa than my Gunite IG pool too--at CA=150 and TA=50. Years ago I owned and maintained a spa and never used Borax. With this...

    Best Places to Buy Liquid Chlorine

    I'm not finding such great end of season LC sales this year, but at the end of last season I bough a bunch of fresh 10% LC at half price or less (mostly at our nearest KMart, which doesn't even have LC this year). Motivated by an LC concentration vs. temperature half-life graph that I found in...

    Epoxy Putty Fail (Suggestions and Advice Much Appreciated)

    I found something that Leakmaster Pool Putter prefers to stick to less than pool plaster. Forget about using the polyethylene wrapper or an applicator cut from an HDPE milk jug. Just like skin or nitrile gloves, the putty prefers to stick to them over plaster. The solution was wax paper! My...

    Epoxy Putty Fail (Suggestions and Advice Much Appreciated)

    It would be nice if I could push out a re-plaster job with some kind of compound or temporary fix. The rest of the plaster is holding up for now. I need to learn what other items should be overhauled at the same time as a re-plaster job. I'd like to have a new concrete deck poured and an...

    Epoxy Putty Fail (Suggestions and Advice Much Appreciated)

    Thanks for your help, ajw22! A bucket test reveals that the pool is not leaking. (I recently fixed a 165 gal. / day underground leak by disconnecting some old defective solar panel pipes but that leak is unrelated to this effort.) The plaster around the perimeter of the two PVC returns in the...
