    Off Season CSI

    Just closed/covered the pool for the off season. I run the SWG to maintain chlorine. Water temp never got lower than 53F last year and I expect pretty much the same this year. Chem levels are all pretty much in the ideal range right now except CSI. Should I do anything to raise CSI or just let...

    Adding A Sump Pit

    When our FG pool was installled four well points were installed to alleviate a ground water issue. They are piped to the equipment pad and so obviously I can’t see where the water level is. I’m considering installing a sump pit near the pool so I can monitor the ground water level. How near to...

    Hayward HP Temp Differential

    Can anyone tell me how to adjust the Hayward HeatPro heat/cool HP temperature differential setting? It isn't addressed in the manual as far as I can tell.

    What is considered “dissolved” CYA?

    I have been adding CYA using the sock method in the skimmer. I squeeze the sock (a skimmer sock) periodically and a cloud is released into the skimmer. Is this white cloud considered ‘dissolved’ CYA? It wouldn’t get hung up in my sand filter causing my CYA level to rise over the next 3 to 5 days...

    No Expiration Date On TFTkit refills?

    I just ordered new CYA reagent and CYA standard from TFTkits and none of the containers show an expiration date. Why's that? I expected that they'd be dated. How would one know how old they are and when they expire?

    Reduced FC Produced With Restricted Returns?

    I picked up one of those generic PVC fountains/sprayers to put in place of one of the three 1.5" returns. Not much spray height so I plugged one of the other two returns to get some more pressure to the fountain. With the next couple of FC tests noticed right away that FC level dropped much...

    Don't Forget To Lay In Some Emergency Chlorine!

    All you fellow Carolinians with SWCGs in the path of Isaias, make sure you have some chlorine on hand in case power is out for a day or 2 or 3. I happen to have 6 gallons left from a slam a few weeks ago otherwise I'd be scrambling to find some today.

    CYA Additions Not Adding Up

    I think I'm prety good at the CYA test. I have the the 50 CYA standard solution to calibrate my eye and I think I'm at least consistent with interpretation of the sight picture when looking for the dot. The issue I'm having is that the Pool Math app doesn't seem to be anywhere near accurate in...

    Metal Test Kits Recommendations?

    We have no traditional pool stores in our area, believe it or not, where we can get water tested. I would like to test my pool and tap water for metals, particularly iron and copper. I see some DIY kits for sale, at Home Depot for instance, but have found no threads in this forum discussing...

    Leave SWCG Generating During Slam?

    Although my pool is clear with no visible algae, I noticed the stairs seemed a little slippery. I did an OCLT and of course I lost 2.0 ppm FC overnight. I never let FC get below 5 ppm with CYA of 60-70 so how algae could have formedI have no idea. That's not the question though. Given that the...

    Jack's Stain Treatment Questions

    I'm about to pull the trigger on treating the pool for iron and possibly copper stains. One of the products included in the Jack's treatment kit is Jack's Filter Fiber Stuff. I'm not really sure what that is or what it is for and if I should be using it or not. Is that added to the filter to...

    CSI too low?

    CSI has been trending pretty low, below -.4. Actually -.51 today. My numbers have been very consistent. Here's todays. Take a look at my logs for previous. FC = 6.5 CC = 0 PH = 7.5 TA = 60 CH = 290 CYA = 70 SALT = 3200 TEMP = 88 CSI = -0.51 Should I be taking action to raise it? Raise PH? It's...

    Going On Vacation

    We're going out of town for 8 or 9 days and the pool will be unattended during that time. I have my SWCG pretty much dialed in, the PH has been rock steady, and the other chem levels don't generally move either. I'm still nervous about leaving it for that much time. I guess my plan at this point...

    Test Droplet Size

    Additional Pool To Track In Pool Math

    I added a 2nd pool to maintain in my Pool Math app. "Pool #2" seems to have carried over all the testing and maintenance records I've entered for "pool #1". Can someone please tell me what I'm doing wrong?

    Do Pine Trees Around or Needles In Pool Raise PH?

    If a pool gets a significant amount of pine needles falling in it, will that cause a noticible reduction in PH? Would one need to add a PH increaser on a regular basis to counteract a resulting PH decrease in a pool surrounded by pine trees?

    FG Pool 'dirt' Stains?

    New FG pool last fall. My water is clear as gin. The chems have been dialed in for weeks now. The problem is that I’m seeing what looks like tan colored ‘dirt’ stains on the bottom in a couple areas that seem to always collect organic debris. A large part of the walking ledge also looks dirty to...

    Zodiac G3 With A Skim Vac Plate or Skimmer Sock In The Filter Basket?

    I haven’t been able to use my (Hayward) Skim Vac skimmer plate with my Zodiac G3 vac. The plate sits high in the skimmer on the basket and I have not been able to cobble together the 45 or 90 degree elbows required to get it turned horizontal and out the skimmer opening and still remain reliably...

    Jewelry Cleaning In Pool?

    My wife wears jewelry in the pool. It seems to be staying sparkly clean now that we're swimming about every day. Is there something about pool water - chlorine?, acid? - that would clean jewelry?

    Organic Matter In A Sand Filter?

    A friend with an IG vinyl pool says that he solved a chlorine problem by changing the filter sand. His FC was depleting rapidly although there was no evidence of algae in the pool or other condition that was causing it. His theory is that there was organic matter trapped in the old filter sand...

    New CH "ideal" Levels

    So the CH levels in the updated Pool Math app are significantly higher than before. I've been holding CH at 280 in my 8500 gal FG salt pool which was about ideal before. Now the ideal is 350-550. Entering the new nominal ideal, 450, into Pool Math as my new target (it doesn't retain that new...

    Zodiac G3 Flowkeeper Question

    I have a Zodiac G3 suction side cleaner. Has worked very well for us. There is a 'Flowkeeper' part which has (had) a pivoting red tab attached. That tab came off and I'm not sure how it goes back on. Can anyone with this cleaner please provide a picture of the Flowkeeper valve showing how the...

    Salt Test Water Temp

    Seems that most chem level tests require one to continue adding regeant until color change stops. Does this not apply to the salt test? Does the sample temp affect salt level test accuracy?

    Pool Math - FC Results and SWCG Level Calculation

    Can someone please explain how to use the pump run time and SWG Cell % calculator in the Pool Math app? Looks like there is supposed to be a drop down under 'SWG Cell %' but I don't see it. What number am I supposed to be plugging in and what adjustment should I be making based on the "Run your...

    Slight Water Agitation Affects PH?

    SWCG Percentage With "Cold" Water

    I seem to be easily able to maintain 6.5-7.5 PPM chlorine with the SWCG set at 4%. This is with water temp in the mid 50s (pool is 'closed', heater off, solar cover on). My understanding was that my SWCG is limited to 20% output between 50 & 60 degrees F. To me this means that it is running at...

    Combined Chlorine Testing Question

    I'm testing for CC using the Taylor K-2006C kit. When testing for CC I add the 5 drops of 0003 and the test sample turns a very very light pink. One drop of the 0871 turns it clear. I record that result as .5ppm CC. I sometimes will leave that test sample as is while I conduct other tests. It...

    Electronic PH Testers

    I had no confidence in my ability to accurately test for PH using the Taylor color block test. Am now using a Apera Instruments PH60 tester. Love the accuracy and no-nonsense digital readout. I calibrate it about once a week but that's seeming like overkill, it hasn't ever been off more than...

    Backwash Frequency
