    Help with Return Jet Fittings

    I have confirmed that I have one return jet leaking right near the termination to our pebbletec pool. For some reason, the plumbing on this return is different from all the others, leading me to believe it's either original (1980's pool) or has been replaced. Either way, I'm trying to figure...

    Total Alkalinity Testing

    I just did an abscorbic acid stain treatment on my pool and am bringing it back to balanced levels. I’m currently doing a SLAM because of some algae. When testing my TA, I’m only getting 30ppm. Is this accurate or does the SLAM interfere with the TA test? I figure it could be this low since...

    Stain Treatment and SC1000

    We have iron staining from the previous owner using well water in our pool. Our pool guy gave me instructions to use absorbic acid, SC1000 metal control, and a culator. I know first to bring my chlorine down to zero and pH to 7.2. Our pool is currently around 60F, but the SC1000 says to use...

    Replacement Pump Reduced Pressure

    This past winter our ancient 1.5hp sta-rite pump finally quit. Due to pump availability (or lack thereof at my local stores), I replaced it with a Fibropool FP150 1.5hp pump from Amazon (https://www.amazon.com/FibroPool-FP150-Swimming-Ground-Horsepower/dp/B07ZQMRX3G). All seemed well but it...

    DPD Powder Shelf Life

    Hi, Can anyone tell me what the shelf life is the DPD powder that comes in the TF100 kit? I've had it for about 7-8 months but the color is changing and it's starting to get clumps in it. Thanks Dennis

    Please Help Me Continue Search for Pool Leak

    Thanks for all the continued support on here for continuing to search for my mystery pool leak. I have been told by a leakfinder company that the leak is in my skimmer/skimmer line. He couldn't find exactly where but thinks its on the outlet of the skimmer. He told me it would be $2k to dig...

    Leaky Valve / Drain Down Valve Diverter Question

    I have a traditional roof solar heater setup that has a Pentair PTV-2TS solar diverter valve with a "leak down check valve" as its called. However, it doesn't seem to always be draining back to the pool. Can someone tell me if the valve will allow for drain back from the panels even when the...

    Kool Deck Paint

    We purchased a home last year with an inground pool with a Kool Deck surface that desperately needs to be painted. Being that we're in FL, I want to be careful not to paint it with something that is going to get hot. Does anyone have any recommendations for concrete paint/stain that can be...

    Where's my water going?

    Okay. I have been having an on-going leak saga for multiple months now. I finally gave up doing my own searching and hired a leakfinder guy to come in. He claimed to have found and fixed 4 leaks and told me that my skimmer line also had a slight leak in it at the entrance from the skimmer but...

    Skimmer Leak and Suction Side Vacuum

    I had a leak detection company tell me that I had a leak at the skimmer pipe connection (somewhere at the the pipe thread connection) and he tried to fix it with some two part epoxy. We'll see if it holds. He told me to stop using my suction side vacuum at the skimmer connection because it...

    Small Leak?

    I've been trouble shooting leaks in my pool now for a few months and haven't been able to seal up most of them but I'm still losing water at a rate of about 5GPH. I determined this using the bucket test and the amount of volume lost in the pool over 48hrs otherwise. My question is, am I going...

    New Pump Selection with Solar Panels

    Before going down a road hours of research, I was hoping someone on here could answer a few questions with regards to selecting a replacement pump (as my current one is on its way out). I currently have a 1.5hp single speed pump for an inground 18000 gallon pool with 2nd story solar heaters...

    OCLT and FAS-DPD Accuracy Question

    I see that for an OCLT the overnight FC loss should be 1.0ppm or less. However, when doing a SLAM with FC in the ~20-25ppm range, how accurate is the FAS-DPD testing? I read that it is +/- 10% accurate. Accurate enough for the lower FC levels, but at 25ppm that can be +/- 2.5ppm. Therefore...

    Adjusting Kreepy Krauly

    I recently purchased a Pentair K60430 Kreepy Krauly Kruiser and went through all the setup process in the instructions. Being that I don't have a dedicated vacuum port I had to purchase a rubber adapter to fit the hose into my skimmer suction opening. The unit appears to be working okay...

    Algae Identification

    I'm trying to determine what kind (if any) algae in my pool. My water is crystal clear but I've noticed that when I brush the bottom and steps I get clouds of green dust that kick up. I also recently washed out our cartridge filter and it was greener than I've ever seen it. I should note...

    Iron Levels

    Can someone tell me if an iron test kit will accurately measure iron ppm when a metal sequestering agent is used in the pool or will it not show the true iron level in the pool? Thanks Dennis

    Myths or Facts?

    I've been using this site successfully now for about 6 months but decided I wanted to tackle some iron staining over the winter (believed to have been caused by the previous owner filling the water with well water). I went to the pool store to pick up some algeacide, absorbic acid, along with a...

    Solution for Brown Staining Streaks

    I recently purchased a home with a ~30yr pebbletec (is what I'm told) finish. The CYA levels were through the roof so I immediately drained over half the pool and have it down to about 90ppm. I know I need to get this lower eventually. The chlorine is about 6ppm and PH around 7.6. The pool...
