Advice needed in buying CO2 Automizer

[RONY11]

I have a Tetratec 700 external filter. The tank hose is 12mm.

I'm interested in buying an atomizer to dissolve the Co2 in an effective manner.

Not sure which CO2 Atomizer should I buy

Aquarium tank CO2 Atomizer system suitable for hose 8/12mm
OR
Aquarium tank CO2 Atomizer system suitable for hose 12/16 mm

What size tank is it and are you using pressurized CO2 or yeast powered generator?

if the hose is 12mm internal diameter, then 12/16. 12/16 stands for 12 internal diameter and 16 external

It is all about your hose size, if in doubt get the bigger size so that it won't choke your flow.

I bought the 12/16 mm to use with a 5/8" hose and it looks a little smaller than the diameter of the vinyl hose, but it works good.

In order to get the vinyl hose to fit on the screw on fitting, I took a razor knife and shaved the ends to about half their normal diameter so that it looks a little pointed at the end-then if fit fine.

When I first hooked it up, I turned on the Co2 and nothing happened. I had read that you need to turn up the psi on the regulator so I turned it up to 20, 30 and then up to 60 psi and still nothing. I put my rubber capped buble counter into a cup of water and found out where my Co2 was going.

Abandoned all my 1/8" air hose tubing and the bubble counter (for now) and I found that the 1/8 plastic ice maker tubing works perfect and can take very high pressure-plus its cheap (about $5.00 for 25 feet at HD) and will never leak.

I keep it at about 25psi.

Very happy with the atomizer.
