...Start with a bubble every two seconds, see what that gives you, then go up from there. I don't think you'll need more than 2bps.

*COUGH* Timmain42 *COUGH* had you listened to ME with the above instead of "1 bps per 40 gallons"...you wouldn't have had your 6.3 problem.
I agree with all else you've written.

Oh yeah..."Anyways i started it at 1 bubble per 2 second, and all seems well..."
