    Lower pH or leave alone?

    I will close my pool on Sunday for the season. Recent tests show all levels within appropriate ranges. With pH of 7.8 and water temp of 55, I get a CSI of -.17. As water temp drops, Pool Math shows that CSI also drops. If I lower pH to 7.6, CSI drops even more. Should I just leave the pH...

    Safety Cover Recommendation

    Looking for a new Meyco Saftey Cover for a 25' x 50' pool. What should I expect to pay for just the cover? Any thoughts on solid vs. mesh covers.... pros and cons? I'm assuming a solid cover would keep the pool cleaner, but would have to continuously pump water off of the cover, whereas mesh...

    Safe to Swim?

    If there is a chlorine residual in the pool (and little combined chlorine.... less than .5) is it safe to be in the water if algae is present in the pool? I know the algae should be addressed by SLAMming, brushing, vacuuming, etc. Just wondering if people should stay out of a pool where some...

    pH at Closing

    Will be closing in a week or two. Noticed that pH has been rising lately… currently around 8. However, I also noticed that as water temp drops the Pool Math calculation for CSI also goes down. So… should I just leave pH at the current level and not adjust? CSI currently at .17 with pH at 8 and...

    Suddenly Seeing Sediment

    Haven't noticed this in my pool until recently. There is a fine sediment that I see gathering in the bottom of the pool. Apparently it is getting through the automatic cleaner and the sand filter. This looks a little like what you get when you use a floc in your pool, but not quite as bad...

    Conversion Costs/ Potential Benefits

    What should I expect to pay to convert my 20,000 gal pool to salt water? I painted my pool this year with epoxy paint and usually get 4-5 years before it needs to be redone. Should I expect any longer life on the paint job if I install a salt water generator? Thanks.

    Pool Math Online Calculator vs Pool Math App

    I noticed there is a slight difference in calculating CSI values when I use the online Pool Math calculator as compared to the Pool Math App. If I enter the same readings, they produce a .08 difference in CSI (.05 vs. -.03). Why is there a difference and which is the more accurate? Thanks.

    Currently, my TA is on the high side at 110, but my CH is on the low side at 250. Along with my other readings (pH @ 7.6, CYA @ 40) my CSI is at -.02 (with water temperature of 65 F). How important is it for me to bring my TA and CH into the ideal range if my CSI is good? If I lower my TA to...

    20 lbs. of Calcium Chloride in 1 day?

    I'm opening today and need to get my CH from about 120 to 250 (minimum recommended according to Pool Math). I picked up a 20 bag of Qik Joe at Ace which should do the trick. Can I add this all in one day?

    Chlorine Date Decoder

    Bought some Liquid Chlorine at Ace today. They are selling gallons of 12.5% sodium hypochlorite for $2.99.... pretty good price! Can anyone decode the date on the carton for me (see photo). I'm guessing that the date is that number on the right near the bottom of the carton, which reads...

    Pool Painting

    I know TFP does not look kindly on painting pools, but it has worked pretty well for me in the past and I expect this will be my last paint job before we leave our home in a year or so. Last paint job was about 6 years ago and I have a couple of questions for anyone familiar with/ experienced...

    When opening my pool in the future I have decided to just replace and lube all drain plug o-rings. Was wondering how important it is to get the specific o-ring listed in the parts manual or if I could just go to the hardware store and get an o-ring that is similar in size and fits the drain...

    How much Algecide 60?

    In the past few years I have generally closed my pool by raising FC to shock level and then covering the pool while the FC is still quite high. I have a bottle of Algecide 60 I ordered some time ago and would like to use it up. Would like a recommendation on how much A60 to add and what the...

    When my deck was redone several years ago, the contractor who poured the deck left a piece of plastic that sits at the top of my tile. This was part of the form to pour the concrete. In most area of the pool it looks good and provides a clean line between the deck and the pool tile. However...

    Feces in Pool

    Just finished a day in the pool with lots of kids and noticed a small amount of fecal matter in the bottom of the pool at the end of the day. I tried to get it out, but it kind of broke apart as i tried to remove it. I have the pool cleaner running in the pool now and FC is at 5 ppm. Should I...

    New Suction Line Cost

    My pump and filter are sucking a lot of air. I have tried all the DIY fixes at the pump and the lines above ground and have been unable to fix the problem. (Even had a pool company out to check it and they could not find an air leak above ground.) Next step is for pressure test/ leak...

    Air in filter

    I am getting air in my filter and not sure where it's coming from. It is a fairly small amount. Usually clears when I open the bleeder valve in about 5-10 seconds. Then, I close the bleeder valve and air starts building up in the filter again. I do also have a little air in the pump lid, but...

    Help with Air Leak

    I am seeing a little air in my pump basket and also in the filter. Not terrible, but enough to annoy me. I assume this is coming from the same source. I ran some water over the pump while it was running recently and it seemed to eliminate the air leak for a short while, so I changed the...

    Leslie's Digital Water Chemistry

    I was at Leslie's yesterday and took a sample of water to be tested to compare to my own test results. The store I go to had a new digital water tester. In about a minute they gave me precise results, i.e., CYA=28, CH=208 vs. the "rough" results I get with my tests. I had calculated my CYA to...
