External CO2 Diffuser

At the outlet, i dun see any visible CO2 bubbles, meaning all the CO2 has been dissolved in the filter canister itself...

Those who are using the glass ceramic diffuser can seriously consider this option. Itz small, doesn't take up any space, and is easy to install... $26 from Plantas Aquaticas...

Airlock? Bro you mean you had installed the diffscer at the inlet of the cannister? If yes, I suggest you change it to outlet.

According to instructions, itz supposed to go into the inlet leh.. from the 3rd pic in this thread...

The canister is supposed to act as the reactor.. I caused the airlock coz i opened the regulator all the way max, and that's like.. 10bps?

Then I think this diffuser will cause alot of problem when high co2 is injected via the inlet.

I think 1-2bps works fine... if we're looking at high volume injection, your suggestion of fixing it to the outlet will be a better idea..

The whole idea of this connected to the inlet is to let the canister act as a huge reactor, i juz double checked again with the guy who sold me this...

Aiyo, then like not very effective leh. You could have invested in a DIY water filter reactor.

Bro, i took ur advise and changed it to the outlet. Affixing it to the inlet will cause my canister to emit funny "airy" swirling sounds previously unheard of. However by fixing it to the outlet now, minute CO2 bubbles can be seen on the surface of the water (i dunno how they came about also, no visible bubbles are seen coming out of the outlet...)

The following pic is taken 45 degrees looking up from below the water surface...

However from the plan (top) view of the water surface, the same bubbles are not visible... probably the lighting, i dunno...

Is there a layer of protein on the water? protein layer tends to trap bubbles. If co2 is alot I guess you got to turn it down.

Nope, minimal protein on the water surface... my CO2 is only running 1bps..

hmmm so it actually does work
