First summer almost officially over with a new pool, TFP method from day one. So far so good. I only test once a week, just go out every night at 9 to dump my bleach in the pool.
For $200 I'd take a flyer (flier?) on the Liquidator. I'm not interested in anything that requires electrical, or putting together systems from multiple parts. Just one package plug and go is enticing. Our pool has high Calcium and needs acid once a week to keep PH low. Any ongoing concerns with "white stuff"?
