Oh, man! What a mess! I figured I'd be using a roller to retract a one-piece cover, so perhaps it might not be so messy. But I also wondered about liability. What if someone breaks in there after dark and gets trapped under the cover? Stuff like that....

Our community pool is heated, with annual propane costs ~$5K even though we only run from Memorial Day to Labor Day. One cost control option that has been proposed is covering the pool at night. My first reaction as CPO was that I have to fool with the cover every morning and evening --...

Thanks, JasonLion. I'll look into the Taylor view tube and be satisfied for now with that level of accuracy. I'm pleased to see that TFTestkits (our preferred seller), stocks a similar product.

I run CYA 20-40 ppm, which is the bottom of my K2006 testing range. The K2006 appears focused on those running their CYA higher. Is there a kit that covers a lower range? And for that matter, if the focus were on a lower, narrower range, is there a kit that reads more accurately (e.g., 5 ppm...

Thanks all! Having trouble getting forum notifications, so I missed your replies. My bad! FC at X ppm above CYA raises the question of accuracy in CYA tests. I practice regularly with standard solutions, and it only makes me doubt CYA testing more. Especially for CYA < 30 b/c my K-2006 isn't...

Drafted to be CPO for NC community pool. Code in our state: "Pools that use chlorine as the disinfectant must be stabilized with cyanuric acid except at indoor pools or where it can be shown that cyanuric acid is not necessary to maintain a stable free chlorine residual. The cyanuric acid...

Thanks, all. I'll pursue and post back if something interesting emerges. Meanwhile, you've taught me a lot already about bucket tests and leak finding.

jblizzle, water levels were near the top of the bucket, so much so that I could only do this test without people swimming and raindrops splashing. So the 1/4" is not likely to be evaporation difference. zea3, I accept your experience that 1/4" isn't significant, and that's what I was asking...

I performed two bucket tests for leaks, during times with no swimming, rain, or water replacement. Both times I got exactly 1/4" difference between bucket and pool water level after 24 hours. Is 1/4" a significant difference? I'm being careful, and results are consistent. I think I may have...

Thanks, Jason! And of course thank you for the calculator itself!

OK. I've switched my link to PoolMath. Looking at PoolMath, seems that oz for the soda ash is in volume, not weight. For example, "Effects of adding chemicals" says 22 oz of soda ash will raise pH by 0.1 and raise TA by 3.1. That seems to correspond to numbers under the "pH" section at...

Pool Calculator is awesome and I use it every year. Question about the section at the bottom, "Effects of adding chemicals". Does "oz" mean weight or volume? I'm trying to estimate effect of soda ash on TA. That's a powder and I guess it could be weighed but I always dish it out in measuring...

If I'm building up the area with epoxy, I might consider also just plugging the hole with epoxy. Sorta gets back to the question of what materials can survive this environment. If epoxy is truly legitimate than health inspector can't complain. So I followed up on Charlie's brass fitting idea...
