FLOW: 65g Tank... to drill or not to drill

The AquaController has one minute resolution. So long as your OM works a half revolution in one minute it might, but you are still at the mercy of a potential AC/DC conversion problem... potential mind you as they may have built this into the circuit.

Sam does make a good point about the lines all being submerged. Once the air is purged out and assuming there are no air leaks in the system, no air can get back in.

So the Aquacontroller has a 1 minute resolution... how about the other "aquacontrollers" on the market? This might be a good excuse to finally consolidate my controllers.

I think for no air to be slurped into the lines they need to be a certain distance under the water line in some proportion to the height of the pipes above the waterline. I'm sure someone knows for certain how that works, but if not I'll run a test of it sometime this week.
