    Getting a new vinyl liner

    After 15 years We decided to replace the liner in our pool despite not having any failures or leaks. (Retiring and wanted to avoid the expense later). We have been using the BBB method of treatment for the last 14 years. Everything is automated with a CAT 2000 system to control FC and pH and...

    Salt in Fresh Water Pool

    In my previous lifetime about (50 years ago) I worked at a chemical company in Houston TX and we made commercial bleach ---- If I remember (and I might not--- senior moments) we used Sodium Hydroxide (caustic soda) (NAOH) and injected liquid chlorine (CL2) into it --- this created an exothermic...

    Salt in Fresh Water Pool

    Thanks --- I doubt if my pH has ever been "out of spec" except when doing stain removal at the end of the season every 3 or 4 years and their are no swimmers when I do that. If anything it'll go high (pH) if I'm not paying attention to the acid supply tank and it runs out. I think the Pool...

    Salt in Fresh Water Pool

    See my signature for pool specs. Location Central PA BBB since 2004 And Ben :-) I add 8.25% bleach (Clorox) and Muriatic acid automatically with CAT based on ORP and pH. Now the issue. I started getting corrosion on the aluminum coping which appeared to be coming from the inside out (Concrete...

    Liquid "solar blanket" to reduce FC loss?

    Just to add my two cents. I would advise against using the liquid solar covers. As mentioned above they are parafin disolved in alcohol. My experience was having little white globs of the parafin floating around in the pool. The pool store tried to convince me it was "White Mold" and I...

    Does bleach go bad?

    I usually buy my Clorox from Sam's Club, but I have gotten some home that was "DEAD" :shock: I took the whole lot back!! By testing each batch I am able to not waste my $$$$. --- 12 cases, 3 X 182 oz per case, $6.50/case -- $78.00 + tax saved. I also found that Aldi is cheap, but not...

    Does bleach go bad?

    Hi LuLu I test every batch of bleach I buy ---- Using 1000 ml (1 Liter) of UNCHLORINATED water (from a well or distilled), place .1 ml of the sample from your bleach bottle -- mix and test. As for the dilution method for testing bleach I use a 1000 ml volumetric flask and a medical syringe...

    CYA test with Hach DR/850 Colorimeter

    Thanks for the input The accuracy range of meter is where I like to keep my pool 25-35 so I'll do some further testing to see how it goes. None of the pool stores in the area can produce acceptable results and have even detected up to 20 ppm in a sample of distilled water I took them...

    CYA test with Hach DR/850 Colorimeter

    As everyone knows the CYA test in the Taylor kits leaves a lot to be desired. Recently I found a Hach DR/850 Colorimeter ($20.00 at a public auction --- Local lab went belly up) . I bought the appropriate reagent from Hach ($17.00 for 50 powder pillows) and ran my first test using both methods...

    What is the consensus of adding "Pool Perfect"?..

    Other than BBB and Muriaatic Acid ---- The only chemicals I use are Pool Perfect and PhosFree bothe made by Natural Chemistry. I live in a high Nitrate area (Phosphates). The combination with BBB has my pool sparkling, no algae, shock once a year (start-up), and the water smells and feels...

    What is sequestering agent?

    Stain If it is Iron, it will respond to Ascorbic Acid almost instantly. Most vitamin C tablets are largely ascorbic acid. Take a Vitamine C pill and hold it on the stain for a few seconds (the longer the better) if your in the deep end it may take some rigging to hold it there unless you can...

    Black "gunk" in skimmer

    I don't know if you are using BBB or pucks but here is a testimonial ---- Prior to going BBB we had the black oily deposit inside the skimmer and also on the steps. The better half scrubbed the waterline weekly and did the skimmers and steps every day. The pool stores said it was pollution and...

    What concentration of bleach in reservoir?

    Your set-up sound like mine. I mix 1 jug Clorox Ultra with 1 jug pool water. I test the solution and normally it is around 3.55%. My tank (15 gallon, light brown & opaque) is outside and in the sun. I have tested when my tank is nearly empty (about a week after filling) and show almost no...

    Another Suggestion

    Would you consider separating SWCG out of the Chlorine Forum?? Also a separate forum for Above Ground Pools might be nice.
