No.. end of tank dump is because when there is no liquid co2 in the tank to keep the pressure up by it evaportaing into co2 gas, the regulater goes funky and lets more gas out.
This is because they are designed to keep a stable rate when the gas is at a high pressure, but when it drops, the regulator doesn't function properly and lets the gas out.
To stop this from happening, when your tank pressure starts to drop, get it refilled straight away.
All taken from that thread.
If there was liquid co2 in your regulator, there would be liquid co2 comming out from it, evaporating in the tube on the way to the reactor/diffusor/calcium reactor because of the loss in pressure.
I asked my contact in OZ about it, And he said that it requires gas, not liquid co2. He also said that when he removes his regulator to get his tank refilled, some gas comes out from where the tank and regulator connect.
Anyway, When I get the tank I will ask that there be no tube in it. They refabricate old co2 tanks, so presumably they can remove the pipe inside if there is one.
I know the height of the regulator from the top of its connection to the tank to the top of the gagues, Warren, If you dont mind could you please measure how high the tank is to the top of the part where the reg fits on.
Appreciate it man. When I get this all set up I will be sure to post pics.
