The only time I've ever had problems with consistency of bubble rate is when the secondary pressure is set too low. Set it at 20-30 psi and always regulate the bubble rate with the needle valve. Don't regulate the bubble rate with the pressure valve. I think it has something to do with the seals in the needle valve not seating properly at lower pressures.

I had this problem with mine too. I noticed that the water in the bubble counter evaporated rather quickly so I removed it and put teflon tape on both the bottom and the cap and all seems good now.

Any new progress? Ive been dealing with a similar issue- When my solenoid clicks off at night, in the morning i will be zero bubbles. Second gauge reads 25# and i have no leaks. Do you think its the needle valve?

TIA

As fishyboy and GG said, I've turned up the output to 30# and it seems to have decided to straighten up and fly right. At least I haven't had to mess with it in almost a week now.

Ive been at my parents home so i'll have to try it tonight. 30#s if i remember correctly is the highest the 2nd gauge will read, so i hope that does the trick. I maybe also be having this problem due to the fact that im using an eheim diffuser.. i stuck it all the way at the bottom, maybe it just takes extra pressure to fight gravity. *crossing finger*

The right guage reads all the way up to 150psi. I keep mine up at 40psi (which is the pressure that the JBJ regulators come fixed at) and have never had a problem with my bubble rate drifting.

Well, I started this thread so I might as well add that cranking the right gauge pressure up to 35psi fixed my problem as well. I also took off the teflon tape I had been using. Even though the directions with the regulator say to use it I finally realized it really does nothing. My bubble rate has been perfectly consistant since then.

I was at 20 psi previously and it was inconsistent. Raising the level to 30 seems to have cured my drift also.

Okay, I'm gonna quote from the instructions as they are sent with the regulator, and is where I at least was having problems:
Turn the adjustment knob (E) clockwise until you get a reading on the low pressure gauge (F) of approx. 10 lbs or less on the inside set of number (psi). You should now see bubbles in the bubble counter. It is recommended that you use the bubble counter rather than the right gauge to determine your flow rate. Only use the needle valve if you can not get exact flow from adjustment knob (E).
The bold and underlining is exactly as it is in the instructions. Now I don't know about anyone else, but to me that sounds like a) you're supposed to keep the pressure on that right gauge at 10# or less and b) using the needle valve is a bad thing! Yet what we're experiencing in the real world is that it's totally impossible to keep a consistent flow with less than about 25-30# on the right gauge, and trying to follow these instructions to the letter, I found (of course) that "adjustment knob (E)" would just close itself up (like trying to get just a steady drip on a faucet to protect against freezing) at such a low rate, barely cracked really.

I guess sometimes there's an advantage to not reading the instructions. :P 30 psi has been the magic # for me.

okay so i turned up the pressure on mine to 40#. 30#'s is the highest my second gauge reads so the needle is way past the 30# mark. This has solved my problem. If it brakes anything i'll just replace the gauge.
