I have water features that I turned on high, and I gave it an hour to mix before testing and adding again. The muriatic acid was 14.5%. I did not check the TA prior to addition of acid. The yellow Home Depot acid did not have the strong fumes like the clear Leslie's. And yes, I double checked...

So I was a little lax over the winter and hadn't paid much attention to the pool pH, but kept my chlorine within recommended range. Today I checked the pH (which I hadn't done for 2 months) and my Taylor kit showed it in the high purple range (> 8.0). I had three gallons of muriatic acid that...

Well, I'm happy to know others use this method too and that I'm not crazy for using the evil tabs as a 1. a source of CYA and 2. ease of use on startup.

I still have to add acid to my pool every 5 days or so. So the Tricolor tabs would assist with that as well. When I go on vacation, I put three floaters in the pool with three tabs. Amazingly, when I return in 7-10 days, all numbers are good. Just gotta be sure my CYA doesn't get too high...

But wouldn't that be a month of ease just using tabs in floaters? That's what I'm thinking. As long as the chlorine levels are adequate with tabs, I really wouldn't need CYA.

What would the experts think of this: Let's say you've drained your pool either partially or completely and refill it. First, you add enough liquid chlorine to bring it to acceptable levels. Then you switch to chorine tabs, which gradually release CYA. When CYA is up to recommended levels...

I have both, and to save time, I use the dip sticks two out of three testings. There is often, but not always, a fair match. Is this a reasonable method, or does everyone here use the higher end kits like the Taylor?

If you have continued problems with this and can't get it figured out, you can call Springs and Sons Electric (‭(602) 242-3500‬). They do nothing but pool electrics and I have been very impressed with their knowledge and work. They are based out of Phoenix, but I know they take work way out of...

Bronze 2hp

A 2hp Pentair WhisperFlo runs about $600. An Advantage Bronze in 2hp is $324. A significant difference for a pump that will never wear out. I don't know who makes their motor but I would guess A. O. Smith/Century.

Has anyone used the Advantage Bronze pumps? They are less than half the price of an equivalent Pentair, and being made of solid bronze, including solid bronze impeller, they have to be more durable than the usual plastic pumps.

I am not an expert like mknaus, but there are only two reasons I would use tabs. 1) if you are leaving town for a week or two and need to maintain FC levels and 2) it is an easy way to increase CYA levels (if that needs to be done), while enjoying a break from adding liquid chorine.

I have actually used test strips to determine CYA levels, but I would never dare state that on this forum, ha! My results posted here are all with the Taylor kit.

I think you are going to need a replaster under warranty. It looks terrible and the contractor could not disagree.

No, I test the CYA with the Taylor kit. And I was surprised that my CYA was significantly lower than last year. Just added two pounds via sock in skimmer. Levels are now 40, so I'll leave it at that for the summer ahead.

I loaded up my pool with Boric acid a year ago and after that it tested 50 with the La Motte test strips. I tested it again today: still 50! I wondered how this could be since I assumed some minor degradation should occur. So I tested my tap water. Result=zero. I guess the strips work and...

I've tried them all. Ultimately, this seemed best overall.

Well, here's an update. As noted above, I was getting flow through my wall jets even when those returns were completely shut off. So while the in-floor cleaning was going on with a psi of 14, I was losing significant flow through the wall jets. Pool guy agreed that it was probably a bad...

The photo below shows my pool return that is divided between a Caretaker in-floor cleaning system and wall jets. The amount of flow to each can be controlled with a Jandy valve. If I close the flow to the wall jets, I still get significant flow through those wall jets. I am assuming that flow...

So maybe the intake plumbing was just filled with air and your hose primed the plumbing.

Excellent! Glad it worked. Did you see what blew out?

JamesW: I ordered two flappers. One thing is still puzzling me. The check valve that you thought was related to the negative edge may not be that. I say this because the negative edge plumbing involves a completely different system on the other side of my pool (not shown). Its plumbing is...

Thanks!

JamesW, thank you for your excellent analysis!
