CYA in a sock

[chem geek]

I weighed the CYA granules on a postal scale and split into two batches, making a one gallon slurry from each and adding one right after the other into the skimmer (basket in place). Granules disappeared from both skimmer basket and pump basket in about 6 minutes.

I want to be clear I understand this. So the slurry of CYA didn't have the CYA dissolve much and when you poured this into the skimmer you didn't have any skimmer sock, panty hose or T-shirt, right? So the CYA didn't all go through the small skimmer holes right away and that took around 6 minutes -- was that for each addition or 6 minutes for both gallons combined?

I wonder how long it would take for some CYA to dissolve in a tube with a magnetic stirrer (I know some of you out there have one)?

Actually, there was quite a bit dissolved in the time it took to add warm water, stir it up and deliver it to the skimmer. The slurry was pretty cloudy so I would guess that about a quarter of the granules had partly or completely dissolved before being poured in. No skimmer sock or any other material in place -- just the skimmer basket. 2 consecutive applications of about 1 gallon each were poured in 30 seconds apart (I followed each with a bucket of pool water to ensure that the granules adhering to the sides were flushed into the basket). It was at that point that I thought to set my timer and kept an eye on the skimmer while the granules escaped/dissolved. I didn't see any granules left at about 5 minutes and only a few in the pump basket -- they too disappeared, about a minute later. So, I'd say 6-7 minutes elapsed from the moment I finished adding the second bucket. During the 6 minutes I entertained myself by varying suction from 0 to 100%, but most of the time it was at mid-point (50% main drain, 50% skimmer).

I should note that the last time I checked there were a few granules (20?) lodged in the transparent Jandy Energy Saver Filter that was mis-plumbed in the water feature (deck jet) return line. This is pretty typical. If I don't run the jets they'll sit there for weeks or months, undisturbed.
