I've been reading your site for the past 2 weeks and following your SLAM religiously for 1 1/2 of those, so I figured I should go ahead and sign up. I live in Southern Ontario (a few hours north of Toronto) and we generally have the pool open from late May-Mid October.
We gained a 16X36' vinyl in-ground pool (~80000 L)when we bought our house in December 2013. My husband was thrilled and made it his project. Unfortunately, neither of us really knew anything about a pool and he spent all last season consulting 'experts.'
The result was a pool that was swimmable for maybe 2 weeks total last season and ended up costing us ~$1500 in parts and chemicals. By the time we closed it, it was a lovely dark green. My husband was pretty discouraged and I wanted to fill the pool in and make a patio. This year, my husband and father opened the pool (still green), re-plumbed the filter lines to remove a non-functioning pool heater, and somehow ended up assigning the pool as "My project" to keep an eye on before work each day.
I'll admit, I wasn't terribly enthusiastic, but I do like a challenge and turned to the internet to make a go of it and found this site.
The SLAM was the first thing I'd heard or read that made sense, so I broke out the test kit and a Giant Costco pail of chlorine and got started.

The photos speak for themselves, so I figured I'd join up and keep on reading here. You guys are already much better than the 2 different pools store we consulted with last year (one of whom sold my husband a calcium additive for our well-water filled pool. )
