As a pool guy that cleans multiple filters every week, I'm not a big fan of Non-DE Cartridge filters. It takes a lot of water and time to clean them well. If you can, I recommend using Pleatco Filter Wash. It is probably very similar to a laundry detergent, but it appears to not have a lot of...

Thanks for your input. Very informative. So I guess the calcium type could be most related to the fill water. Your instance of tile cleaning is rare as to introduce calcium sulfate into the water it would seem. I'm no chemist but it sounds from reading that article that phosphate scaling...

Thanks for your insight. Would you always consider those white flakes to be "scaling" of some sort? I hopefully edited your post above correctly. I assume you meant to put High in there, yes? I have done the acid test many times over the years and it always Fizzles like Alka Seltzer, so...

Re: White flakes in pool from SWG : YouTube Video In the article I post a link to above it says this... "The phosphate connection So, what is going on when phosphate levels climb in a salt pool? We need to look to the industrial uses of orthophosphate in water treatment. First of all it is...

I would really like to know the exact cause of the white flakes that are produced by the SWG. I have 40 salt pools on my route and only 2 (this year) got some of the flakes. Why do some pools with SWG produce them and other not? And I do a very good job of keeping the water LSI balanced. I...

Is calcium a metal? Gather up some of the white flakes an pour acid on them.

I would like to recommend to Pentair that they redesign the cartridges that they put in the QuadDE filters. I have over 20 fairly new QuadDE filters on my pool route. What I am finding is that the rings they use to hold the pleats apart are not even lasting the first year. And within a...

The 100 PSI pump requires the check valve. That's what matters.

Stenner does not recommend the 100psi version for swimming pool application, just so others know in the future. And 100psi versions are not allowed in commercial swimming pool applications. The check valve assurance is unjustified as propgated by some here.

This is a dog's pool only? Pretty nice of the owner to keep the pool at 90 for his dogs. Your not sure of the exact type("some sort") of "nasties"? Clean the filter. Determine your CC, and super chlorinate as needed.

I'd like to offer suggestion but would need way more info. How are you determining your salt level? What is the pool water temp? What is the %? What is the exact CYA? How big the pool? All the other chemistry? What do you mean you are losing chlorine? How many hours run time and speed?

Did you get a 100 PSI pump? What exact pump model did you get?

450 CH should not make that much difference, especially in one day. I have a 2 pools with CH that high and TruClear that I installed, and they are fine. What is your complete chemistry test results?

You are probably correct. I was just thinking/hoping that maybe off chance someone here had ran into a brand of union that was a match. For all I know, maybe the end on the eBay one is not a "perfect" match and the threads or sizing could actually compromise the existing Pentair nut if...

I guess not. I just looking to make a few dummy cells for pennies on the dollar, not plumb loops and such. thanks anyway
