This tank and regulator combination uses a Tap-Rite #742 two gauge regulator.

Appears to be Clippard MNV-4K2 (4k2 has an 1/8 hose barb included)

or

Florida Driftwood shipped my valve with a 10-32 to 1/8 NPT adaptor on the bottom port.

 

Connect Needle Valve to Regulator

If needle valve comes with brass adaptor with 1/8” NPT male screw threads:

 

Also needs a ¼” NPT male to 1/8” NPT female adaptor (Clippard #15006-5) to connect the valve directly to the regulator.

Can probably get where you fill co2 gas.

 

If needle valve does not come with any brass adaptor – std 10-32 male threads on bottom:

 

Need ¼” NPT male to 10-32 female adaptor (Clippard #15006-3) to connect the valve directly to the regulator.

 

Add second 1/8” hose barb to needle valve

 

Add female 10-32 to female 10-32 bushing (Clippard # 15004)

Add 1/8” hose barb to male 10-32 threads (Clippard # 11752-4)

 

CO2 Reactor

Plant Guild Power Reactor

            Scroll down or look for “power reactor”.  I use the larger of the two products.

 

 

CO2 Level Monitor

Dupla monitor - Dupla CO2 Dauertest

http://www.dohse-aquaristik.de/dupla/england/dupla/produkte.php

 

or

 

http://www.dohse-aquaristik.de/     and select “Dupla Products”

 

Then search for “dauertest

 

Initially I used this and it saved my but.  Once the co2 is stable, there is less/no need for it.

 

 

 


NOTES

You may be able to buy the Clippard needle valve - MNV-4K2 from a local Clippard distributor. Check their web site
www.Clippard.com

 

The web site can also show you the closest distributor to where you live.

 

 

To add a second 1/8-inch needle connector on the Clippard you need the following parts from Clippard:

 

#15004 - Female Hex Connector - convert the 10-32 male inlet port to a 10-32 female

 

#11752 - 10-32 to 1/8 inch hose


Some people use other co2 reactors/diffusers. Lots of variety here so do some more research on the web.

My 5 lb tank lasts about 6 months on my 55 gallon tank.

 

Be sure to look at local welding supply companies and at home brewing supply stores for tank and regulator.  Certainly will save shipping (partly offset with tax).

 

Note if you consider buying a used tank, be sure to find out when it was last pressure tested and how much that will cost.  As I recall, tanks must be tested every five years.  If possible, get a used tank that has had a recent test.

 

If you are interested in less pieces, be sure to look at the Milwaukee and JBJ all-in-one regulator-solenoid-needle valve units.  You just add a tank and you are all set.  Some people swear by them.

Do a Google search for “Milwaukee co2 regulator” or “JBJ co2 regulator
