two days ago, I’m just opening the pool and found my pH low (using a Taylor big kit): FC:6 PH:7.0 TA 65 CH 250 CYA 75. Pool Math app suggested 9 pounds of 20 mule team borax. I put in 4 pounds, even though I don’t have borax in my pool. I happen to have an unopened box, so I used it. I have a...

The unit is 13 yo. (cartridge) I've replaced the big o-ring twice, well lubed it, scrubbed each hold-down with scotch-brite on the filter and the clamp things, and then sprayed with silicone to allow them to slip forward for clamping action and still get leaks in various places. I have a...

I've just restarted my system after a refill. The SWG appears to be working - no flow light, then green generating light. When I switch to superchlorinate, that light comes on. But my display shows 5.00, then it changed to 5.60, now it's at 5.90. Nothing happens when I push the diagnostics...

When I clean my filter, water continues to come out at a large trickle. There's a Jandy check valve (automatic shutoff of water flowing back) after the SWG and a Jandy diverter valve (manual shut off) before the main pump. I've replaced the check valve and no difference. The pool store...

I'm having my pool Pebble Sheened in a week. Because of delays, the pool has been empty since January (I'm in NC). It had some black algae in the pool before. I've told my pool builder about that, but I want to make sure that I've done all I can to ensure a good success here. Should I...

Hi, I'm re-plastering my pool with PT and had black algae before. Therefore, before putting things back in the pool, I thought I'd make sure they were "clean". One thing I noted was black spots on the Polaris and I can't seem to get them off. Are these mold or something? It's been in...

I have a flooded system with one of those Jandy check valves that's supposed to shut off the water. I've replaced the valve thing and it's still leaks when cleaning the cartridge or the strainer. I'm planning on putting in mechanical valve of some sort because it's a huge drag for water to...

I was told by a very experienced pool guy that SWG and Well water were not a good combo. I have iron and manganese in mine (an old gold mine is on the property). I have a greensand treatment for the house, but still have to clean the iron/manganese off the toilet bowls every few months, so I...

Hey everyone, My pool is plastered SWG that's 12 yo. We have well water and have staining from iron and manganese (the property has an old gold mine on it), and it appears that there's some scaling that occurred that trapped minerals to cause the bulk of the staining (Jack's stain test shows...

With the pump running on a 24 hr basis, I've had a major water loss. It was 6 inches below the skimmers by the time I noticed it. I shut off the skimmer valve at the pad and the leak stopped. I've tried it with the pump running and not running - no leak (I'm following TFP leak detection with...

I don't have any power output between the 2 yellow wires. The troubleshooting manual says this means the rectifiers are bad, but I don't think so. I've a tester for diodes and it shows .4V or .8V in one direction only. This manual seems to test the transformer only by measuring the...

I'm on well water on an old gold mine parcel in NC. The original fill was from a reservoir and top ups are from the well filter through iron filters. I also adjust ph slightly trying to maximize the efficiently of the filters but still have pool staining. Even with the filtering, the water...

I know I have iron and lots of manganese in well water. When I'd top off pool, the pool would turn that green that you see before an algae bloom. I used to think that and would shock. But a smarter poster than me pointed out algae doesn't grow in the dark. Today I topped off and sure...

Here's the numbers: FC: 2 PH7.2 TA 70 CH 175 CYA 30 I have brown large area stains on the steps, shallow end and part of the deep end. I had first thought iron or manganese from the well until i used Jack's stain test id kit. The iron packet #1 (and some AA I had) did nothing, but Stain...

I have a thread under Algae that is related but I felt a specific sequestering question is better here. Every time I top off the pool with well water, I get a color change to a greenish tint that looks like the beginning of algae bloom. I've always thought it algae, but algae doesn't grow...

Hey, Does anyone have any experience trying to pull water from a creek or perhaps a pond? I have a small creek and a utility tractor with loader and was thinking about either using a pto pump and running a hose up the hill or filling a tank and bringing it up. I have manganese and iron...

Hey, I could use some help. FC:not sure - just shocked to a target of 15 PH: 7.2 TA: 80 CH:250 CYA: 50 Salt:3100 I just finished an relatively unsuccessful ascorbic acid treatment. I used 3 lbs, when FC was close to 0 and I thought PH was at 7.2, but I used a test strip and I think it was...

I'd appreciate some help. I currently have some iron staining on my plaster SWG, 24,000 gallon 8-year old pool (cartridge filter). The iron comes from topping off with well water. I do not have borates in my pool now, and would like to establish them at 30-50 ppm. I have 3 pounds of ascorbic...

I have a 24,150 gallon in ground plaster salt water pool. 8 years old. I bought a t-9 cell two years ago and it's been a problem since. My salt readings are off and the chlorine generation is very low to nothing. I can't get any chlorine reading on the outlet. All the lights seem fine and...

I just bought a salt test kit to check salt level for Aquarite SWG system. SWG shows 3100 ppm, but the test kit shows 7000 ppm. I check the test kit against free water and it seems to work fine. Would other levels - chorine - ph - CH affect the test? The reason I'd added salt to start...

I thought this would be an easy switch over but my brain is fried. I had a single speed max-e-pro and replaced it with a 2 speed of the same model P6RA6YF-206L. I have a Aqua Rite SWG and a Intermatic T104R. 1. I thought the new pump would have a toggle for high and low speed, but it...

I have a 21000 gal in-ground with a Sta-Rite System 3 cartridge system with 2 inch piping. I have a pool cleaner but it has a separate booster pump. I've got a flood system but only by 5 feet. No spa or fountain, just the pool (gunite). I have a SWG. Currently I have Sta rite max e pro...

I've just discovered the world of TFP, bought a test kit and and trying to get in balance. Data: SWG Aquarite in-ground plaster 2 years old 24,000 gallons; Taylor 2600 test kit Temp:58 deg F; Green Algae present on walls; suspicion of black algae in crevasses; Vitals: FC 3.2, PH 7.85, TA...
