Hi Keith;

I've never used a Liquidator unit, because all my work with bleach was on large pools. But, after years of setting up bleach feed systems, I'm pretty familiar with how the LQ unit works. So, with that caveat, here are some answers:

1. Given the way the units work, there should be no difference in effectiveness, just in capacity.
2. Can't answer that. I *can* tell you that the trend is toward SWCGs and away from all other types of feeders.
3. Maybe. If your 12% bleach was fresh, and actually 12+%, then yes. In s. Florida where lots of pool companies sell bleach from tanks that are filled daily from a manufacturer's tank truck, you can get full strength fresh bleach. In my area (Chattanooga), the only way to get fresh bleach is to take a tanker truck delivery (5,000 gallons) from the nearest manufacture, about 70 miles south of here. It appears you are in New York. If so, bleach 'cook off' (it breaks down rapidly when liquid temps are 90 degrees or higher) would not be as bad as in Chattanooga, or points south.

Finally, about SWCGs -- you want to look carefully at your pool before you get one. If you have steel pipes, I would recommend against it . . . and I'd also recommend keeping an eye on your salt levels, just from chlorine use.
