So last week in preparation for a gathering I pulled my cover off my pool (thereby dumping a huge amount of **** that had collected on top into my pool).
With the addition of the large amount of crudness in the pool (which was clear before I pulled it off) I was worried about the load on the chlorine level in the pool, and decided to bump up the SWG to 100% for a couple of hours (I was out of bleach on hand) until I could go get some bleach from the store.
The debris in the pool was mostly these very fine husk-looking things from my blooming neighbors trees and my two cypress trees in the back of the yard.
I checked the salt level, and it was at 3000, a little on the lower end of the scale for my swg.
After a few hours I got an alert that my SWG was shutting off due to low salt. (???) and I checked and it was at 2500. I added my emergency bag of salt and let it mix.
A few hours later I checked again, and it was at 2000, EVEN LOWER! ?????
I hadnt drained any water in weeks, and had only added enough to replace evaporative losses.
I wonder where my salt went?
After vacuuming and cleaning the pool, I discovered the husk things had made it through my skimmer basket (forgot to put on the nylons) and filled up the pump basket slap full, and was starving my pump.
I wonder if the husk things have some sort of salt-absorbative properties? Anyone heard of anything like this? Salt just disappearing from the pool?
I checked both with strips and the readout from my SWG (which is never exactly right but usually pretty close within 1-200ppm.) and they agreed that my salt had fled.
