got in the clippard valves and got my tank refilled. Checked every connection with soapy water this time. You would not believe the leaks I found! But they are all stoppped now. It ran all night with no problems too. Hopefully it will continue to do so. Those Clippard valves really do make difference. 8)

Actually, while they're better than plastic valves, quite a few of us have had lots of problems with the Clippard needle valves. Read over on the AquaBotanic forum and you'll see. People are looking at $80 monitoring valves and whatnot. I for one have had lots of trouble getting my Clippard valve to sit still. It still won't.

I think that people having problems with Clippard valves are in the minority. I can only think of maybe two-three people that have had problems with them. The APD is full of people using them and you never see problems. I have sent out at least a dozen and know many people locally using them and only one person that I know or helped is having a problem.

Good points, Rex. You know, ginnie, he's probably definitely right about my case being an isolated one. I just still have it fresh in my mind how people on the AquaBotanic board are looking at $100 alternatives to the $15 Clippard Needle Valve because they're having the same problems I am. I think it scared me pretty bad...

and using two valves. My frustration level with this was at its max. I wanted to set it up and not worry about it anymore. Now the only thing I have to be concerned about is the tubing staying on the needle valves. I think I'm going to get some sealant or something to make sure it does.

I have never had a problem with the tubing staying on the barbs. But if you are worried about it get some small hose clamps. Don't use sealant!

IMO and IME the problems associated with using the Clippard needle valves stem from not matching the pressure from the regulator to the valve correctly. Some regulators work fine with 5-10psi, I can only get a stable bubble rate by turning the regulator pressure up to 30psi. I feed two aquariums, a 55G and a 75G and never touch the needle valves between refills of the CO2 cylinder. I can't imagine a better needle valve regardless of the price. Finding the correct mix of pressure and needle valve can be a bit of trial and error but once achieved the settings should be almost maintenance free.

That is the point I want to get to! I'm feeding two tanks also. A 38g and a 75g. So far so good. My psi is is set at 8 my lowest setting. The first valve is almost completely closed and the clippard is used for fine tuning.
