Oddly found a simple solution, I had a little CO2 based air tool set that came with a regulator, but well haven't used it other than the one time I needed it and to clean my computer cases. No clue why I didn't think to use it in the first place, I'm usually the type to just use whatever I have laying around before going out to buy something. Kind of handy really think the setup ran me about 60 bucks or something came with the regulator, a little air hose forget what else really some O rings and the like. But no less system is working fine now, going to return the ASA fitting and just get a second CO2 tank so I don't have to worry about making it to the store if it goes out mid week.
(( NOTE:: Has a lot of bad reviews people saying it tends to leak air, I stuck mine in a bucket of water to check for leaks, I don't have any, maybe I will down the road but so far no leak. ))
I think I got mine on sale for like 40 percent off awhile back.
But still less expensive than some of the ones designed for aquariums, fittings are a bit of a pain. I think I've four or five connection points to get it into the needle valve lol. But it doesn't leak. So no big deal. No less Pressure issue solved.
Total cost of my setup.
24 for Co2 tank
50 for the regulator -- 89 now since its not on sale
then about 10 or so for fittings and needle valve.
So somewhere around 85, probably could have gone cheaper but thats ok, this seems more precise than running the needle valve off the asa fitting.
