Hi guys, My hand rail was installed in April of 2022, so it's about 3 years old. I just noticed that it started to rust, but only at the water line. Do you know if it has to do with that white stuff on the rail? I don't know what it is - calcium, salt?… I'm sure that with some effort I can take...

Hi guys, My pool was completely remodeled in April and I got an SWG (IC40). I started getting some calcium flakes coming out of my returns once a week for the last couple of weeks. I tested my water and my TA has crept up to 100 and pH is noticeably "pinker" than the 8.2 level on the pH test. I...

I use TF-100 test kit. Two months ago my CYA was 60. Today it is down to less than 20. I filled the CYA test tube to the top and the water is cloudy, but I can still see the black dot. I measured a second time with the same result. This is confusing because as far as I know CYA doesn't decrease...

Hi, I replaced my pool equipment "pad" and filter. In the process, I tore out electrical connections because conduits were in really bad shape. I was planning to fix it myself - all I need is the pump, timer, and the pool light. But when I posted on another forum, they noted many problems with...

Hi, I'm replacing my old pool filter, which returned water through an old Leslie's Coppertherm heater. I've never used the heater and it was filled with all kinds of dry leaves and dirt. So before plumbing in the new filter, I decided to test if the heater works and either connect it to the...

Hi everyone, I'm replacing my old pool filter. There is this closed (squashed) vertical copper pipe near the return pipe. Nothing was connected to it. It continues for several feet, then connects to a PVC pipe and goes under the slab. Does anyone know what it is? Could it be connected to sewer...
