I have a combination of factors that make me think that I may be better off not lowering my water level for the winter. I have a Pebblesheen pool with a sun shelf that's about 15" deep. When closing my pool last year, I lowered my water level down below my returns which put the water level at...

I have four pipes each with a Jandy Neverlube valve coming into the suction side of my pump (spa, main drain, and 2 skimmers). While the pump is running, if I close off one or two of the suction side valves (thereby increasing the vacuum pressure), I get a burst of bubbles in my pump basket...

I currently have a single-speed Jandy SHPF1.5 that I want to convert into a two-speed for the energy savings. I believe the SHPF1.5 has a A.O. Smith B842 motor, so it appears that the B983 is proper two-speed match. Does that look correct? My heater and SWG need a 30 GPM flow. Based upon my...

We are in our first full season with our pool. I'm quickly learning that our pool builder didn't understand the finer points of pool equipment. I am considering replacing our 1.5 HP SF 1.5 (Jandy Model SHPF1.5) single speed pump with either a two speed or a variable speed pump. I currently...

First, I'd like to thank the moderators and contributors on TFP for the invaluable information and help provided here. Friends laugh at me when they see my pool chemistry set and (homemade) magnetic stirrer - until they see my pool. Everything seems perfect with my pool except that my Jandy...

My numbers a week after opening: FC 4 CC 0 PH 7.5 TA 90 CH 320 CYA 45 (Slowly moving it up to 70) Salt 3300 Borates 30 Temp 62 F CSI -0.41 With all of the great guidance from this site, I think I've gotten my pool well balanced, except I'm worried about the CSI being as close to -0.6 as it...

My new pool was finished about 6 weeks ago, and since then, I've been working to apply the great information that I've learned here. Below are my test results. Please let me know if there's anything you think I should adjust. FC: 3 CC: 0 pH: 7.5 TA: 90 CH: 340 CYA: 70 Salt: 3500 Borates: 50...

I'm a proud new owner of a TF-100. Everything is going well except for my alkalinity test. I'm getting readings over 300. I believe the problem may be that the droplet size that my R-0009 reagent bottle produces is atypically small. In fact, it's very hard to squeeze the bottle gently enough...
