Thanks BlueRam. I've seen those, and think they are a reasonable value solution. (I bought the better of my two peristaltic from those guys)

Problem is the "through the bulkhead" thing. Nothing else is going through a bulkhead without tearing down the tank. So I figure that's out now. And I'm kind of adverse to putting equipment in the tank anyway. That's why I find that new thread of Tom Barr's (about the CO2 microbubbles), it's all leading back to more crap in the tank. I don't like hiding stuff. I'd rather have as little as possible to hide.

Also, the range is kinda high. It's got that "dead band" that zzapd mentioned of 1.5 inches. Just like mine, it has to drop 1.5 inches before it know there's been a change (mine drops 10-12 though!). With 1/2 inch variance, that could be a range of 2.5 inches. Not terrible. But I'd like to get it tighter if possible.

But thanks for beating that horse!


I've got to try the "air pump" on a "T" that I mentioned a few posts ago. It just might work...
