Thanks for the reply.
Anything is worth trying so will give it a go tomorrow.
What’s so frustrating is the fact this is like a rattle at cold start up in a car. Once you have started it and the engines hot, you need to wait until the next morning to try something new again.
I will give this a go, anything is worth it as I’m simply trying to solve a simple problem that’s from A to B, but I just can’t see the issue.
To add this is the second brand new diffuser and housing , so it would be really unlucky to have 2 that don’t work. But I’ll try anything!
The left side absolutely clears quicker, I’ve watched it, but I’ve always determined this is because it’s actually working off the correct 2 bubbles per seconds at CO2 on, so it’s pushing more up the tube quickly, where as the right hand side clears slowly because it’s only working off the issue of 0.5 bubble per second and stays like it.
CO2 is on at 12pm tomorrow, so I’ll strip it down again and seal the end of the ceramic tube carefully with PTFE and see what happens...
When the Co2 kicks in the left side instantly starts bubbling away at 2 bps and starts Clearing the pipe or any water and then the diffuser, it’s like it instantly has the pressure from the CO2 cylinder to drive the CO2 up the tube.
The right hand side no matter where I set the needle valve night before even spinning it open a whole turn still feels like it has no instant pressure to get the bubble rate going, but having swopped cylinders round with the whole assembly attached it just can’t be the cylinder issue.
I’m so confused...
