Hi. We just purchased a home with a pool that was not maintained and is currently very green. We put some type of chemicals (a trichlor and something before that) from Leslie's for the last 2 days after we took a sample there, but then my friend told me about TFP. I've read the SLAM article and have the Pool Math app. When I tested this morning, the CYA was quite low as the black dot never disappeared. The app is saying I need to add 11 lbs of dry stabilizer and 3 galloons of chlorine. Is it okay to put some dry stabilizer in a sock in a skimmer and then liquid chlorine in the pool? I've been ready that you shouldn't use both at the same time, so I'm not sure how we would raise both levels. How much dry stabilizer would you add at a time since I imagine it will take quite a while to get 12 lbs added. Thank you!
