So, I keep seeing 12V solenoids.

Why? 12V all look like similar wattage to 120V. However, at 0.1x of the voltage you would get 10x the current. This would seem to be more likely to cause heat...

Dealextreme solenoids

Anyone seen these? Any ideas on these?

Seems like a bunch of 220V stuff, which would probably be better for heat.

Odd that another post is talking about Saf-t-Sorb.
If you want soft water(which usually means low pH), just use that as a substrate.
