I never liked the ones where they were incorporated. Always trouble for me. I also have substituted the brass collar for the vinyl one when using vinyl tubing. Seemed better but that could be just me.

jrill Your missing the collar that goes over the tube. That's were that compression part comes in. I see its may be there but could be damaged. Get a new compression collar.
On a second thought are you trying to use standard aquarium tubing. That's like 7/32 as opposed to 1/4. Sorry I did not read the whole post.

Basically, the standard airline is 3/8" it fits nice and snug over the bullet part that nestles into the valve. When you slide the nut with the built-in compression ring on it, it screws onto the valve nice and tight, but there is space all around the airline. The hole in the nut/the compression part is too wide for the airline to be airtight. What am i doing wrong?

EDIT: Here is what i mean about it being loose:

creekbottom Cv values are a pretty good way to tell, there is a pretty good discussion going on here: http://www.plantedtank.net/forums/sh...d.php?t=837474

Hilde How do you know you have the right size needle valve for this setup?

Do you have a drop checker? I still think your fish would be fine at 1 bps.

I can't comment on adding a solenoid as I have no idea whether your proposed idea would work.

But if you can swing it financially, I'd look into the Aquatek mini regulator which is for paintball tanks and comes with an integrated solenoid.

Here's about 2 weeks of growth. 1 week with my paintball setup and 1 week with my 20 pound/regulated setup.

I figure as long as I have a 1 way i don't have anything to worry about.

All I can find our setups that have built in solenoids. Can someone PM a link to a good setup similar to the Paintball setups from Aquatek that doesn't have the Solenoid. I don't care to have it shutting on and off and I'm starting to max out on electric and would like to plan on it just running 24.7.

No problem.

I'm not sure of other manufacturers that make paintball tank regulators, but Aquatek makes one that you don't need an adapter for.

Amazon.com : AQUATEK CO2 Regulator Mini : Paintball Regulator : Pet Supplies Amazon.com : AQUATEK CO2 Regulator Mini : Paintball Regulator : Pet Supplies

Also, a solenoid doesn't necessarily mean that you have to have it turning off and on. You still need to hook that solenoid up to a timer to get that on/off cycle. If you just plug it straight into an outlet it'll run 24/7.

I also think the key to keeping that consistent bubble rate is a quality needle valve. I got the cheapo one from Home Depot and for one, it's really hard to make micro adjustments.

The issue is that a quality needle valve can start running you around $50 which makes this less of a cost-saving method.
