Ben,

Thank you for following up. I retested the pool at the local store around noon and got the following numbers:

Free Chlorine: 5 (I know it's > 15ppm at this time)
Total Chlorine: 5 (I know it's > 15ppm at this time)
Calcium Hardness: 400
CYA: 120
Total Alkalinity: 150
pH: 8.0
Total Dissolved Solids: 1500

I know the "what would you do" questions are typically subjective to each individual but I'm trying to look long term and determine what is in the best interest of the pool and its maintenance needs going forward. I'm concerned that by finishing out the 70+ lbs of tabs I have that I'll just be compounding my future issues and besides - I can sell the tabs for what I paid for them so I wouldn't be out anything. Couple that with the fact that I have a child who has very sensitive skin; I think it would be best to do a partial drain and get the numbers back down. If I look at this reaslisitcally I'm just whining about doing something that my family is complaininig to me about messing up in the first place... of course I'll never admit that to them - HA!

I'll rent the sump pump tomorrow and get to work. If there is something I'm missing please let me know! Thanks again.

One final question for my own clarification - outside of dilution (and of course rare earth elements that I can't get anyways)... is there any other cost effective way CYA can be lowered in a pool? From my reading I don't believe there is but wanted to ask.
