How do I check that?
The regulator is only on hand tight to the fe as my adjustable was too small. Couldn't detect a leak though.
I have a check valve before the bubble counter too. Is that necessary?
Well I've just tested the reg to a bit of tubing just into a glass of water and it was doing exactly the same.
So should I assume it needs tightened?
Its normal for it to fluctuate when it turns on or when you adjust it, it takes some time for the pressure to establish in the tubes does it still jump up and down after half an hour?It's gradually dropping pal
Let it settle, it will slow down a little, then increase a little more, only a touch at a time until you get the level you are looking for, check the drop checker also and not just the bubble rate, bear in mind that the drop checker is about 3 hours behind with the readings, so only adjust a little at a time and might take you 3-4 days to get there but that way you won't wipe out your livestock.When adjusting, do the bubbles eventually slow down when the system is building pressure? It starts off faster then slows. I'm guessing that's why I need to leave it to settle.
Make sure you using the needle valve to adjust the CO2 also and not just the knob on the regulator, get the pressure about 2-2.5 and then use the needle valve to adjust the CO2 and leave the knob on regulator alone.Cheers.
It hasn't even come out of the atomiser yet. Taking its time to build up back pressure for that.
