Thanks for the vid posting. With my test it never did disappear completely even when filled to the top of the tube, so it looks my my cya level is really low.

And yeah Kel, mine is connected to the pool by an waterfall-like opening. In fact, the main pool return lines might be somewhat clogged because the jacuzzi drains faster than the pool which is making it act like a skimmer. Don't know if it's supposed to be that way but it brings all the floating debris into it making it easier to scoop up with the net.

I hired a local pool guy to 'show me the ropes' about the equipment and everything (how to remove and clean the filters, and add DE) until I could take over. He's the one who cleaned out the green slime pit when the house was vacant for 4 months that I originally posted about here. He's quite popular and hard to book for an appointment, almost like a doctor. He added muriatic acid for the ph and TA, but then he put in some blue liquid he called 'kill it' (he's spanish and that is what it sounded like he was saying) and the pool became a foaming mess that took two days to clear up, but it is back to sparkling clean now. Told me to buy a floater for the chlorine tabs but I'll go with the bleach method for now, although I can see why just keeping a floater filled with tabs has it's appeal.
