I shut off the main needle valve and don't have to mess with anything when I
turn it back on.

Good, I'm glad I don't have to keep the green silicon tubing anymore. I
thought it was the special stuff for CO2.

Sorry I must have missed that amongst the slew of other posts.
I still think you are doing too much work by not having the regulator shut
down at night. forces you to have to mess with the needle valve daily.  If
it works for you then cool personally I wouldnt like having to set my bubble
rate every day.

Silicone is the worst for CO2. I forget the exact figures but it loses like
20% effeciency per foot. lots of wasted CO2. as well over time it hardens
and splits. Vinyl will also degrade over time just not as quickly as
silicone. Poly is the best. And is what is used in commercial CO2 delivery
systems.

What I have been doing (for the third time) is shutting down the black screw
top that comes with the tank. If the valve to shut of the whole tank is a
needle valve, I would be surprised. So, I think the correct term for what I
had been doing is turning off the main valve.

BUT, Erik's suggestion worked, which actually was to shut of the
needle-valve instead of turning off the tank. So, NOW, as of today, I am
shutting it off using the needle valve and with the pressure lower, like 10
or 15 psi instead of 20.

I thought silicone was better than vinyl. At least, that's what June
Olberding used, and I got her stuff for taking care of her 20-30 planted
tank room. If I am wrong, someone please correct me. She has blue tubing
going from regulator to the main needle valve and I am using about two
inches green silicone tubing from the needle valve, to the check valve, then
to the line reducer for the mini-vinyl line to the diffusers which are
placed in the aquarium and make CO2 bubbles which make the plants grow.
