After suffering with Baq for the last few years I am ready to switch. I started last season by withholding the Baquacil and leaving the pool open longer than usual to aid decomposition. I used sodium monopersulfate regularly during that time. I did not want to chlorinate as I have a DE filter and was pretty sure that I would not be able to remove the resulting goo effectively. Upon opening I changed about 70% of the water as added insurance. My pool now tests at zero Baq (pool store test and my own strips). I also poured bleach into a bucket of pool water and got no reaction whatever. Therefore, I have concluded that I am Baquacil free. I will also clean and soak my filter to make sure there are no remnants there.
Now what? My water was tested at the pool store (I ordered the test kit, but it has not arrived yet). The water is relatively clear, a little greenish, but not cloudy:
I am ready to go, but would appreciate any last minute advice before I start adding chemicals.
