Good read. I believe the issue closely resembles calcium nodules. The resurfacing was done over marcite around 2012. There was concern about the prep work before the pebble was applied. I guess I'll just keep brushing it off. One 2"x2" area the plaster came off and the edges now grow. Thanks...

I have these build ups. If I address them promptly, they are soft and easily brush away. If I wait, they harden and require a stone rubbing. Some are pebble like, others are streaks. All no matter when I address them, they leave the surface smooth and white where the blemish was. They tend to...

Humbly I bow and shake my head. I swapped the test cylinders. After a ride up to P-A-P, their results were close to my usual results. When I got home I tested again, and as soon as I got the kit out, I realized my mistake. Their CYA was 90, we never agree on that. Please moderator, feel free to...

I called the local P-A-P, all their pools samples are indicating low TA. Their data shows recent rain is acidic.

I've been using the TFP app for a few years. My TA, once I quit chasing, has been steady 80 for months. The CH has been steadily dropping to 350 for even longer. The PH hardly moves, I add 1/2 cup acid once a week and maintain 7.8. (Keeping 7.8, not lower, is what I attribute to the TA...

Thanks, I'll be getting a new cell sooner than later. I am hoping the tropical storm will drop enough rain to bring the salt level down.

Install was 11/2017 - I got my hours Hayward Swimpure Extreme T-15 940 cell; serial 4E17180-201316 Salt level = 3700 P-A-P; my strips indicate 4100 but they are a few years out of date. Voltage off = 31.4 First cycle - V 25.5 A 6.39 inst -3100 Second cycle - 26.2 A 5.02 inst -1700 From what...

It's been two weeks and the pool looks great! I'm still having to supplement liquid chlorine but only a cup yesterday. The pool chemistry is in the recommended range. I had reason to visit the pool store, so I took a sample. There results were different but primarily I wanted to know about the...

As I've read, yes. The purple stuff bonds with the iron and keeps the iron off of surfaces. The SC 1000 is a chelant and also bonds with iron. The difference, as I understand, is the sequestration creates a larger bond than the SC 1000 and will filter out. There are many posts from members way...

It's been a week and a half. The result is great but not what I expected. First - for all of the past year my choice of metal control was Orenda SC 1000, this year I am going to use The Purple Stuff. Second - The Purple Stuff costs more; maintenance doses are higher and there is the (dreaded)...

Thx, I already had it bookmarked!

It's been just over a year since "My Iron Stain Removal" thread. Since I have well water, I have staining again. The noticeable staining is really only on the drain covers. I removed them once and cleaned them with muriatic acid and looked good for a while, but the staining gradually returns...

WREC is 11.4 cents per kw. Noise is not a consideration, pump is 30 feet away inside a building. No response on whether or not my 1995 sta-rite dura glass is any less efficient than the newer pumps. So I'll assume that is a wash. If it ain't broke, don't fix it.
