Jimrahbe nailed it. Consistency is key. As an example, I used to test CYA outside on a sunny day near Solar Noon, waist-high testing, etc. I found after comparing outside vs inside CYA testing, there was little to no difference in the results so I now test CYA in my kitchen under fluorescent...

Thanks (y)

The Smart Stir looks like it would be a good spare to have in case my Speed Stir goes bad, Is the Smart Stir compatible with the Taylor 9198 Vial?

Thanks (y) . Since removing the 3 main overhanging tree branches, the Pool Aphid/SAP issue is basically gone along with almost all of the Squirrel Pecan debris. One thing's certain; the SLAM process works like a charm :lovetfp:. The main point I've learned during the few SLAM's I've had to do...

I live in the Dallas-Ft worth area (Tx) & I had the same problem for several years when I had 3 main Pecan Tree branches overhanging part of my pool. I cut those branches out of the tree & have had much better Pool balance results since that time. It also greatly reduced the pecan debris...

It appears there is a wide variety of the Glycerin-Filled Gauges' life spans. With mine, the failure mode is usually the same; not reading Zero with Pump Off (after trying the "Bleed" Orfice opened). I haven't seen a correlation of failure with cold winter weather. After a very hard long...

Location : DFW area 15k Gunite Pool, ~30% shaded FC Dosing : 10% Chlorine TPF methodology Dosing Frequency : May - Early November : Every other day November - April : Varies from every 3 to 6 days My average FC Depletion Rates : May : 1-2 June : 2-2.5 July : 2.5-3.25 August : 2.8-3.0...

stslimited84 I built a rig to compress the Spring in the Top Assembly for most models' Multiport Valves. The info is in this thread : https://www.troublefreepool.com/threads/need-new-spider-gasket-help.247065/#post-2166768 It works ok but is time-consuming and the Wing Nuts are a little tough...

10-4 (y) . Those Glycerin-filled 0-30PSI Gauges are great. They eliminate the issue with condensation that plague the plastic-lens Gauges & the scaling (0-30) is so much easier & more accurate to glance at when checking the Filter Tank PSI.

Location : Dallas area, Tx It's been a few years since I tested CYA in/outdoors, water temps, etc so I decided to repeat the tests to see my results. I switched to Indoor Testing July '20 after numerous testing showed that the differences between Outdoor Testing, on a clear day around Solar...

"10-4" on the Glycerin 30 PSI Gauges. I switched to them years ago & although I've had 2 of them go south (reading >0 with Pump Off/Bleed Plug on Gauge opened, etc) but the 3rd one has lasted >4 years to date. One of the benefits besides the ease of reading the PSI (30 PSI range more accurate...

I'm in the Dallas-Ft Worth area in Irving, Tx. I've stored my Bleach in my Garage for many years without any measurable potency depletion when I test the pool dosing results (with DPD Powder). I usually buy in bulk cartons since, as of now, I've not seen any shelf/storage potency loss with my...

Thanks (y) . I installed a hand-tite 7/8" OD Compression Fitting close to the Valve outlet so I can disconnect the long tubing length when I have to remove the Tank Top for Filter Maint. I'll keep the 5/8" ID Tubing connected since I already had it working with the Heat Gun to expand it a...

Thanks for the info :) . I was thinking it was 3/4" ID.

I have a Pentair Fiber Tank 180007 (36 Sq Ft) that I had installed last July to replace a leaking 35-Yr old Nautilus Stainless Steel Tank. The Pentair Tank is running great but I have a question about the 98209800 High Flow Manual Relief Valve Barb Outlet where one can install an extension...

By coincidence, after reading this thread, for the first time I noticed a light brown ring around the 10mL mark in my Taylor (P/N 9198) Vial. I put some 70% (Gro Store/Pharmacy) IPA on a small paper towel & rubbed the inside of the vial with it & the brown ring is gone. (y) for another great...

JamesW : Excellent point about the spare Grid Set Assembly. I have 1 built spare & a couple sets of individual Grids (complete set of Grids un-assembled) in my pool parts stock. I like having them available for fast troubleshooting spares. I can then clean the used set when time permits...

The problem could be that the "Top Vave Cover" part has some wear on the sealing surface, the inner circomference area where the Diverter Shaft O-Rings seal against the surface to prevent water leakage at the top Handle area. I have a Pentair MP Valve 261152 with a Top Valve Cover 271169 . I...

Good advice from proavia . I've been using the Glycerin-filled Gauges for 7 years. I've had a couple go bad (not reading 0 with Pump off after trying the 'bleed' cap - venting the internal gauge fix) but the 2 main advantages I see with these gauges is one that proavia mentioned & the other...

Snowman255, Thanks for the suggestion. I have an unopened R-0870 .25Lb Powder Jar in my stock which I'm expecting to be clumped as it's been on the shelf for a while. The Mortar/Pestle idea sounds perfect for this issue.

I re-tested my Unit Dose Dispenser, comparing the difference with the Taylor Blue Dipper Spoon. My UDD dispensed about 2 Dipper Spoons of powder, with one spoon with a little amount of "heaping" spoon content. The other spoon was level in content. If I recall as it's been several years since...

(y) I also consider this tip to be one of the best ones I've used from this forum. I marked my PVC Pipe with a large black Sharpie marker at the 1-foot point to give me a visual mark of the pipe's depth into the pool water.

I also use the Unit Dose Dispenser. I know it dispenses more powder than required but the convenience (for me) offsets that issue. I measured it once compared to the small spoon & the difference wasn't as much as I'd expected but it's been a long time since I've duplicated that comparison...

Thanks for a fantastic comparison chart (y) :salut:

I get most of my Bleach at Home Depot DFW (Irving, Tx). I store it in my Garage unless there are extended sub-freezing temps during the winter. Then I move it into the house. So far, I've not seen any shelf-life/temp/storage issues with either 8.25% or the Home Depot 10% Bleach. My FC tests...

Hi, I'm in the DFW area in Irving. I usually buy my Bleach at Home Depot Store # 0563 Zip 75061 . Lately it's been in stock so I stocked up for the summer. Julian Date is 22 013 Mfg'd 01/13/22 .

Same as Jimrahbe, I keep my CYA at 50 . I keep my FC a little higher than the 6-8 range, usually around 9.0 .
