The reason I asked about how you drained was in case this was somehow done with pool plumbing, so perhaps a valve was left slightly open, or a siphon effect was still ongoing... However, if you used a sump pump, and then removed it afterward, that idea is a non-starter. Perhaps the junction...

By what method did you drain down to your desired water level (just below skimmers, as you said)?

Matt, I don't know anything about balneotherapy, but I do like math, so... just a question about the above calculation - 2.3% ( x 10,000ppm/%) = 230ppm I agree that 10,000/1,000,000 is 1%, so that looks right. What happened to the extra 0s in the multiplication, though? Why isn't the result...

It sounds more like a leak... 12" of water is a lot; that much water can't just have disappeared into the plumbing. Did you have any signs of a leak during the swimming season? Does the pool have an auto-fill?

I thought it was a brief and humorous concession 'speech' :D Plus photo to help out future readers as well as the OP :goodjob: I'm still trying to picture the flow path; i.e. how the filter apparently still functioned as a filter, but with the DE on the inside of the grids...!

One drop on the 10 ml sample means 0.5 ppm for FC. If your K-2006 is like mine, there are instructions in the lid of the box... with the 10 ml sample you multiply by 0.5, with the 25 ml sample you multiply by 0.2 For the CYA test, the more CYA your water sample has, the cloudier the...

Thanks for your input! I was beginning to think this was the case - i.e. that these in-water alarms are on the market primarily to satisfy regulations, rather than to effectively increase safety.

I'm having a few regrets about leaving the pool up to wait for this 2-speed pump (which won't arrive now until tomorrow, according to UPS tracking). With a forecast for temps below freezing last night, I was outside around 11 PM putting the plugs into the pool inlet and outlet points, and then...

Well, a weird and interesting story for sure! Also interesting that another poster had basically the same experience. Did you get heater bypass valves plumbed in while they were correcting the error? Or did you not see a need for the bypass function (question addressed to the original poster)?

Appears to be in South Africa...? 4-6 cm water loss in a week is quite a bit. Depending on the climate, it might indicate a leak. If the weather is hot and dry at the moment, it might be normal. Try doing a 'bucket test' -- essentially filling a bucket with water, setting it on a step in the...

Are there any units particularly recommended for this purpose? To be honest, I don't think such an alarm is all that useful in our situation - we are on a back lot, way back from the road, woods in back of the property, and older neighbors (no children) on both sides. That might lead us to get...

Here it is: AG105.7 Pool Alarm. No building permit shall be issued for the construction or substantial alteration of a swimming pool at a residence occupied by, or being built for, one or more families unless a pool alarm is installed with the swimming pool. As used in this section, "pool...

I recently got information from our town's building department, regarding requirements for AG pools... like many owners of a 'blue blob' pool, we are starting to think there may be a larger, permanently installed AG pool in our future. The electrical, bonding, and fencing requirements were all...

The 2-speed pump has been slow to ship, but tracking now says it should be here Wednesday, so I probably will give it a quick try when it shows up. The pool is still up, and we have no frost warnings in the forecast for the coming week. So, I'll probably be packing the pool up around Halloween...

I was thinking more that the sand might be too fine for pool filter sand. If the filter is indeed almost empty at this point, perhaps you should take the opportunity to inspect the laterals for damage or cracks that could be allowing the sand to pass. When you changed the sand, maybe some of...
