First post here and let me say thank you for everyone with all the helpful posts. I'm so sick of going to my local pool store and giving them half my paycheck only to find after 3 years that it isn't working for me.

I have a 20 x 40 vinyl pool at 33000 gallons with only two return lines for circulation. The filter is a Hayward s240 series with a 115/230 V pump. The pool is in the sun for 90%of the day and maintained a temp of about 85 all summer.

As far as chemicals go I have been following the advice of a pool store being at opening dumping about 50lbs each of stabilizer calcium and alkalinity as they call it. Then shocking the pool with the gallons of bottles that appear to do nothing. I also buy the 3 inch pucks that I stack up in my chlorinator and blast on full like they've told me. Then once a week I shock the pool again with 4 gallons of the liquid solution. The test kit I use was either they're in store service or the terrible strips.

As per the store all my readings are "perfect" however my pool was very cloudy and green. I've tried multiple times vacuuming to waste to no luck. Running out of options I decided to hire a pool cleaning company next year until I found this site.

I've already gone ahead and taken your advice to buy the k2006c kit which I'm waiting to arrive. I've put my pool on hold until I get the kit. I need to get it clear so I can winterize it.

I suppose my question is, when I get my kit in and find my levels, where can I find the best price accurate chemicals to follow the BBB method? From what I remember reading I think you said get great value 8.25% bleach from Walmart and borax and baking soda from a hardware store.

Thanks!
