    Balancing (Pool water looks dull)

    Opened pool yesterday. Tested chemicals several times today and yesterday. FC: 13.5 CC: 0 PH: 7.6 CYA: 30 CH: 210 TA: 100 No debris left in pool, just water look dull.. should I try to lower TA a little? Could that cause the dullness?

    Pool Math App-Inconsistencies

    Hi All, Quick question. When looking at the PH section with a current PH of 7.8 and a target PH of 7.2 using 31.45% MA it suggest I use 8.2 oz to lower to my target level.... When going into the effects of adding 31.45% MA it says that adding 8 oz will lower PH by .1... Any idea why there are...

    If I am leaving for 7 days, what is the best way to care for the pool; lets assume I have no one to come over and put chlorine in on a daily basis. I have an inline chlorinator that will hold roughly 7 3" tabs and I can purchase a floating chlorinator to hold an additional 4 tabs. Would you...

    Pentair 320 In-Line Chlorinator

    Seems like it’s leaking from the bottom. First time I removed the chlorinator, I didn’t realize that there was a set screw, so I’m assuming I damaged something (diverter tee?). Is there a way to repair this without breaking into the plumbing and replacing the diverter tee? Not even sure if this...

    Fiberglass Pool-White Chalky Residue

    FC: 8 CC: 0 TA: 110 CH: 350 PH: 7.4 CYA: 80 When I brush or rub the walls while swimming, a white chalky residue comes off and disappears. Any idea what this is and how to fix it? Pool is about 8 years old. Thanks, Mike

    PH Increase

    Seems like my PH is rising daily and every couple days I am having to pour MA in the pool to bring it down from 7.6 to 7.2. FC: 7.5 CC: 0 PH: 7.2 TA: 120 CYA: 70 CH: 320 Any idea why my PH would fluctuate so much? My TA started at 160 at the beginning of the season and I have since brought it...

    Normal FC loss

    FC:10 CC:0 PH:7.2 TA:140 CH:340 CYA:80 I am losing about 4 PPM of chlorine daily. Anything to worry about? Pool is crystal clear. Just seems like a lot to me. First year using liquid chlorine with no tabs. Having to pour almost 100 oz of 12.5 in daily.. could get real expensive. Pool depth goes...

    Taylor Test Kit

    I think I read somewhere that you can use 1 dipper of R-0870 instead of 2 when testing FC with the 10mL sample. Is that true? Would the FC show differently if I used 2 dippers? Just curious.

    Chlorine Feeder

    Does anyone here use an automatic chlorine feeder? If I use the chlorine feeder on a daily basis, how quick is my CYA going to rise? I have always used the feeder in the past, but never really understood the FC/CYA until last week. It really seems like a pain to have to dump liquid chlorine in...

    Water Chemistry-Free Chlorine

    Pool has been opened for about a week and I cant seem to get a free chlorine reading. Pump has been running 24/7. When I initially opened the pool it was light green/blue. Tested the chemicals at Leslies Pool and they told me that I needed to pour in roughly 30 pounds of shock to kill the...
