The best place I have seen them is Tropical World Pets off of Watson in Crestwood. There is also a place calles Aqua World in Ellisville but they are hit and miss and the owner is grump most of the time.

Hi, I'm in St. Louis and looking for Otocinclus Affinis (dwarf suckermouth catfish) - I'm having a lot of trouble finding them here. Any advice on shops that know what I'm talking about when I ask for them?

okay. great help man.
Thanks!

There are hosebarbs that I purchased from Swagelok on the input and output of the needle valve.

You just need to screw the regulator onto the tank. Easy as pie.

Yepee!

Two last thing though, bro.
1--How do you connect the both ends of your Swagelok needle valve to the CO2 tubings? Are those piece part of the Swagelok?

2--Can you please send me pictures that shows how the regulator part connected to the CO2 tank? I just need to understand the connection of CGA-320. You know, Sumoregulators are telling me things that I could not understand about Concoa connection to the CO2 tank.

If it doesnt bother you, can you please email the pics to limhg@hotmail.com

Thanks for your help bro.

You got it.

Yes, the cross looking thing is a swagelok needle valve.

I see. Im getting a clear picture here.

So, from your CO2 tank you have these connections/ fittings:
I would name it--

1st--CGA-320 Nut and Nipple Fitting
2nd--Your Concoa Regulator
3rd--4" long steel pipe with 1/4" male fittings on both ends
4th--Solenoid
5th--1/4" NTP male fitting with 1/8" hose barb
6th--CO2 tubing
7th-- What is this "cross" piece ? Is this a neddle valve?
