Hope this long ramble helps.

don't you clean the pulp out inbetween fills?

when I built my first reactor I make it hold 55 lbs of ARM so I only had to clean it and refill once a year

as for bubble counters.. make your own. a chunk of 2" dia tube, about 6" long, seal the top and bottom and drill two holes in the bottom to accept JG 1/4 to 1/4NPT tap the holes put a chunk of tube that goes to almost the top of the unit and then put a plug in the top face for filling. use glycerin or mineral oil inside the bubble counter instead of water unless you have one of thoes silly ones that automaticly fill the bubble counter with water.. if so I am sure you can disable this feature. and finaly spend the 20 bucks on a good 1/4" needle valve and use this to control the bubble rate. so all ou are using you regulator to do is put a specific pressure out and you use the good brass needle valve to set the bubble flow.

using a more viscous fluid will make it simpler to set your bubble speed. I know mine I would set the bubbles then re adjust after about an hour after the pressure inside the reactor stabalizes then I would check it once a week.. went 8 months with out touching it.
