For the moment, don't worry about pH. Yeah, it's high, but that may be due to the TC being so high and it's falsely elevating the reading.

Do not, not, NOT add anything but bleach/Liquid Chlorine at this point unless Ben, and ONLY Ben, AKA PoolDoc says to do so!


In my opinion, you need to raise your FC to 15, minimum, and keep it there. Given that your CYA is 50, at the top end of the 30-50 scale, you could even take FC to 20ppm safely.

You still have stuff you have to get rid of in your water even if the Bacquagoop reading is zero. It's still all over your system, and you have to get rid of it.
That is why, I think, you have such high CC levels. You should see, after a few days, the CC reading come down. When it's zero and stays there, you are finally done with your conversion.

At that time, you'll have to clean out your filter. If it's a sand filter you'll need to replace the sand, absolutely. If it's DE, you'll have to clean the grids, maybe even soak them in Muriatic Acid (I'm not the DE or cartridge whiz). If it's a cart, I don't know if you can clean the element or have to replace it, but if you can I expect at a minimum you'll have to soak it for a day or two in electric dishwasher detergent. Any cart users out there that have done the Baq to Chlorine conversion?
