I just converted to SWCG from a Liquidator a couple weeks ago.
One reasoning for doing so was looking at the fact that I don't always refill the LQ when I should. I'm using 5 gallon jugs from our nearest Namco, which is ~20 miles round trip. The 5 gallon is decently price (16.99 + 6.00 refundable deposit), but since its 12.5% I dont like having more than one or two of them at a time, since it will degrade quickly. Through a whole season Id make probably 5 or 6 trips with 2 jugs each trip. Since I only use my truck (dont want this stuff accidentally spilling in my car), at 14mpg and 4.00/gallon all of a sudden that starts to add up too. Factor in the fact that I have to work with the big jugs, make sure I dont bleach clothing, etc, and SWCG became more *convenient*.
I can do math and make the numbers better for a SWCG, but the fact of the matter is that liquid chlorine probably will always be cheaper, but not more convenient. Its also nice having a unit that will compensate for water temp as its been kinda funky up in the Northeast lately (94 one day, 80 the next, etc) so it keeps a pretty steady level without any interaction from me. I dont think the "feel" of the water changed noticeably, maybe because I was already using liquid chlor.
Since mine is so new it remains to be seen how reliable the exact system I got is, but so far Im quite impressed. Like I said, I just dont need to touch anything anymore. I keep testing the water but havent seen anything change (including the pH), so its been a good two weeks!
