Gentlemen, thanks very much for the detailed description of bleach chemistry (very helpful) and the Stenner observations and recommendations. FWIW, my Stenner is several feet above the chlorine tank liquid level and pool return pipes so I gambled I'd be ok without the check valve. However, I...

My Sun2solar 1200 series (measures 9mils and made by Toile Soleil in Canada) last more than twice as long as the several others I've tried. Key difference is their bubbles are dome rather than "deli cup" shaped. My experience has been that that the "deli cup" bubbles fail at the sharp corner of...

Marvelous reply. Thank you! By "salt" do you mean Sodium Chloride or other salts like, Calcium? I assume Sodium from the Sodium Hypochlorite decomposition into the air? I will purge the tank and monitor things. I have no check valve in the tank > stenner pump > injector to pool return...

I have to drill (5/32") out the black plastic injector every 10 days or so due to plugging with the same sort of white deposit that plagued my prior liquidator setup. The removed deposit dissolves in water acidified with Muriatic acid. Diluting the bleach with water into the Stenner from 10...

No "magic number of turnovers per day". Schedules are for volume that I vary summer, spring/fall and winter based on what works and sweep, air purge, freeze prevention etc. Again, the question is whether others see cycles fail to execute and why? Thanks.

E.g. I have three cycles programmed, each later in the day, the forth is latest of all. Three cycles are enabled. I'm seeing the third not running at all despite the cycle time being needed to achieve the pool volume set. Volume:30K Three Enabled Cycles: 5:20am - 5:50am 6am - 9:50pm 11pm -...

I understand Calcium Carbonate solubility to DECREASE (unlike other salts) with increasing temperature. So I'm thinking my recent bout of WS was precipitated (pun intended) by CYA of 60, chlorine to top of LQ's white tube below funnel, CH of >350 and pH too high of near 8 AND high (100F)...

In addition to pool school:black algae teachings, I've found this works to address small patches on flat horizontal to near horizontal surfaces. Put ~1/4 trichlor puck in middle of mat with rib side of mat down. Cover area of combat with the mat. Restaurant supply stores have these cheap. Else...

Dory. C'mon, our 380 sweep is blue :)

Very useful, useable and complete app. Thanks so much! Some humble suggestions/requests for additions when you want to have some "fun" programming ;) 1. My muriatic acid is 14.5% (from OSH) which ain't on the list. Might you add it please? 2. Might you add some additional "measure" fields for...

Re: recommendation for East Bay,CA contractor to replace ski Thanks. I've had the work done by a friend that prefers to do commercial work. 20 years is a pretty long time.

Yeah, Pentair has a problem documenting this pump. Here's what I found: - suction face to midpoint of discharge = 10" - floor to midpoint of suction face = 9" - floor to discharge face = 11 1/2" Good luck.

I order a single bag on the phone from local Fastenal and they have it for me in ~ one week. FYI, Calcium Chloride sources have been discussed a lot on the forum (search Dowflake, Peladow Tetra94). There are a variety of recognized acceptable options, but what you can get at a reasonable price...

So to wrap up this saga... To clear blockage, I had skimmer and 1.5" lines to/from pump shed replaced with 2". Workers threw out the line before I got to see what blocked it, but it was a bunch of sharp bend elbows and even some flex tubing! I tore out and re-plumbed/wired pump shed with...

Welcome to TFP! The 50# bags of Excel Calcium product I bought locally at Fastenal (see my first post for details) works great and was much less expensive than I could find anywhere else.
