I don’t have any idea why the last part of my reply is in all caps. Sorry, it was a mistake.

OK, but it is a little disturbing that Pool Math app said to put in twice the amount of borax that I put in and it seems to be way too much. I need to be able to trust it. And, yes, I know about the low FC. THE WATER IS COLD, AND IT’S TRICKY TO GET THE SALT WATER GENERATORS TO GET THE RIGHT...

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...

yes to both. And I put it on superchlorinate and could tell the FC was increasing - Everything seems to be working fine. The display board is $102 on Amzon - ouch. They have an aftermarket for $68 but I don't know - only 5 reviews.

I removed and cleaned the display connectors, and now it shows 5900 (and won't change with the button). The main control panel is about a year old, but the control box/unit (the system) itself is about 12 years old. I guess I need the display panel.

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...

Thanks but I've decided it's flowing back through the booster pump and am installing a ball valve on the 3/4" pvc feeder. If that doesn't work, then I'll be back with the photos.

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 read some "related articles" after posting this a few minutes ago. I'm pretty sure it was black algae. When you rubbed it, it would smear a blue-green color and it was primarily in the cracks of the plaster, around the tile pieces on the steps, etc.

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...

Shoot - I missed your other post above - never mind about the bonding thing. Thanks.

No, you've done enough, thank you. I'll find them. I already use an injection system (soda ash solution) to adjust the ph of the house water, and it was also in the $300 range. It actually would work fine by simply putting it on a landscape light timer. It's adjustable and comes on when the...

That's why I post questions here - knowledgeable people with no interest in the outcome. Thank you for the time it took to read and dissect - it's truly helpful to me and I'm sure others. I am pushing this issue because I'm re-plastering and am very (very) worried about staining. The...

I'm having my 12 yo pool re-plastered with quartz finish and the pb is making a point out of using Basecrete instead of Bond Kote. Is there value in this distinction? If so, how much $ for a 550 sq. ft surface? I do have some small spots of black algae, but I wouldn't think that matters.

Avoiding stains in salt chlorine pools - AQUA Magazine.

I came across this article in Aqua magazine. It seems to indicate there are staining issues associated with SWG.

Yep, as much as possible. BTW, I tried to understand the Pourbaix diagram...maybe get the gist but not much more. What may be more interesting is the manganese. It's level is so high (after the whole house filter) that my local county is not recommending we drink the water. I could...

Thanks man. Replacing the water with city water is definitely in the plan. I intend to put a quartz finish to help with a good surface, and so this was the time to decide whether to continue with SWG. I can go with a Puck dispenser plus bleach for a while - its easy to switch to SWG - just...

Actually, I've spent years on staining and am very familiar with the issues. I had not heard of SWG making it worse, which is why I asked. I have found the PH management issue myself and that may have contributed to the staining since I was not prepared to manage the ph so often (the pool...

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...

Thanks a lot for your thoughts. I think the most important part is the few years. It costs $1500 to refill the pool, and $1K for the acid wash, so even more than I first thought. And your point is that acid washing sounds like it will shorten the life, which adds to the problem. I spent a...

I somehow missed this response. I'm sorry. My latest numbers are: FC 3.2 PH 7.6 TA 110 CH 230 CYA 55 As to hard water, some but I'm not sure how badly. We do have some build up at the bottom of faucets, but after 12 yrs, I've cleaned them maybe twice. So it's definitely hard, but it...

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...

For the record, I misused my testing and finally got a VDC on red and black (after replacing the rectifiers - unnecessarily). At that point, it had to be the board, which I replaced and fixed it.

Thanks again for the help. Line to line is 244VAC. Yellow to Yellow is 24VAC. Orange to ground lug shows proper voltage. So I now checks red and black wires according to the troubleshooter and it shows no VDC (should be 18-33 VDC). So this takes me back to the rectifiers. I only have one...

Thanks for everyone's help. You're right, I checked DC on the yellow. Darn. I'll check again tonight. BTW - my tester has a diode setting, and I have an extra bridge rectifier and tried that anyway. I've got no lights or display of any kind. I also didn't check the orange/ground lug. -...
