Whats up with my Bubble Counter

[Westyggx]

Hi All,

Alistair gave me a new diffuser yesterday which you can see below.

My bubble counter is acting weird, can anyway tell me why its doing this (stopping and starting with the bubbles) i have currently set my pressure from 1.9 to 2.5 to allow the new diffuser to work.

Cheers

Hi Westy, I had my bubble counter do this once when I put in a super atomiser. I opened the regulator as far as it would go but the bubble rate in the counter wouldn't increase. I put it down to not having enough working pressure even though it was reading about 2.5 bar. I put my glass diffuser back in and it worked fine.

The injection rate looks too fast on the 1st video as the bubbles are rather large. I had the same happen with one of those super diffusers. That or atomiser is shot.

This could have something to do with the C02 tube (air line) expanding before the pressure build up enough to force the gas out through the ceramic & them build up again?
I would try some high pressure tube.

Yeh alastair said it could be the co2 tubing but I bought it from aqua essentials and sure it was special co2 tubing.
