CYA test with the K2006 was off the scale. I had drained 12" of water from the pool, and refilled today while running the pump.





Learned today that the PO had set the pool pump up to only run 4 hours a day.

Also....in the myriad of valves and plumbing by the pump there is a valve which is troubling me. It says "Skimmer" and "Drain".

The bottom of the pool has what appears to be a drain (about the same size hole as the skimmer basket) but it has a cover screwed down over it. If I turn the lever on the valve from skimmer to favor the drain side, the pump starts cavitating quite a bit.

Could the drain be capped off? And why the heck would you do that? I want to dive in the pool and unscrew it, but I'm a bit apprehensive.....why would someone cap off the drain in the bottom of the pool ?!?!?


Algae is getting worse. Came home with 2 gallons of 8% bleach from Lowes. Should I dump one/both in tonight?
