    Should I uncover my pool now?

    Temps are warming up here in North Carolina. Tree pollen is kicking in. I think if I keep cover on I wont have to worry about running filter, algae, adding chemicals cleaning strainers of pollen,etc,etc. Water is still way to cold to swim for awhile. Any thoughts as to a good time to uncover?

    How long does it take to clear?

    Opened my pool about 10 days ago. CYA is 70. Ph was about 6.8 (added 200lbs of salt to get it up to 3400 ppm) Alkalinity is 90. FC was pretty much 0. Immediately dumped required amt of 6% bleach to bring to shock level of 20 ppm (pool calculator numbers). I know Ph is low,but figured salt would...

    How much bleach to reach shock level?

    Not to sure how to convert ppm's into gallons of bleach.I understand bleach is less corrosive to use than dichlor(way more convenient size wise). The pool calculator tells you what level in ppm's, how do I convert that into how many gallons of bleach I need to get. Ive got algae and calculator...

    Mysterious stains in deep end of pool?

    I was playing a fetch game with my kids yesterday with swim goggles and when I went to the bottom in the deep end I noticed several tiny ( BB-size) blackish spots which did not come off when rubbed. In fact some of them appeared to be eating away at my liner as they felt indented. I managed to...

    Filter Debris

    My pool is located around a bunch of trees. I am constantly getting debris in my skimmer which is small enough to get to my pump basket. My concern is this tiny stuff is eventually making its way into my filter and will eventually contaminate/clog it. Is there any kind of finer screen or mesh I...

    CYA and backwashing

    Just opened the pool about a week ago and with a little TLC got it back to blue and clear. I took a sample to my local pool guy and as I figured some of my numbers need a little tweeking, as expected. My question is with my CYA a little low (55ppm) and the fact that it is SNOWING POLLEN , I...

    Water temperature and opening pool

    Just took the cover off my pool here in North Carolina, vacuumed up debris remnants on bottom. Water is a little cloudy. My question is with water temp below the point where my SWG will not produce chlorine, can I go ahead and shock, adjust Ph/Alkalinity, adjust stabilizer etc and just use...

    Supplementing Chlorine for my inop SWG

    I have a couple of questions concerning my SWG pool. I have a Pentair IC-20 Saltwater generator giving me an indication that the salt level is low ( with this indication the generator is NOT making chlorine ). When I test my salt level it is reading approx 3000 ppm. When I call my pool rep, he...
