I have a green pool and was told to get the k-2006 taylor kit. I tested the CYA and it was way to high on it. So I mixed half tap water and half pool water and it tested 100. So 100x2, my CYA level is 200. I need to drain and refill probably a few times. My question is what is the safest amount to drain and how do I drain. I have a pool that's 16x32 with 8 ft deep end and 4 ft shallow end. I have a sand filter that can be set on waste. Do I shut the skimmer line and drain to waste?
Edited: For anybody who reads this. My pool store said I had a 70 CYA, when I really had a 200 CYA. For anybody going through this.
