Using the canister filter to increase the efficiency of CO2

[shrimp]

As I am using a two feet tank hence the Co2 tend to reach the surface very quickly. I think this will cause it to be less effective.

To solve the problem I can probably get an extend Co2 reactor.

But what if I use my canister filter to suck the Co2 into the canister and pump it back to the tank?? Will it be more efficient, or will it cause the filter to spoil?? :huh:

Making canister as CO2 reactor. Then you will kill all the bacteria inside the canister. Since the canister full of CO2.

I see... thanks for the information. :-)

Then in you guys' point of view, what is the most cost effective way to induce Co2 into your tank?

Can share your Co2 setup?? :)

Heard the external CO2 reactor working better than internal reactor. Personally, I am using 2 reactors for my 4ft. Mean...the canister outlet connected to reactor A. And then the reactor B connected to reactor A with a joint.

sounds interesting... hope you can provide some pics when you are free :)

maybe I can set up in the same way.

Either a reactor or a diffuser will work. I did a combo of both on my current design.

Pics of it.

Co2 inside a canister doesnt kill off the benefical bacteria dom^^ if so, then that means a CO2 enriched water would also kill off the bacteria..which i dont think is true. ive been running CO2 into my filter / HOB and home made Canister without seeing an ammonia spike nor anything weird.

alot of people just feed there CO2 straight into there filter as they find that it works great. but u just have to make sure ur canister filter isnt AIR LOCK which means. if air gets in, itll just stop working. so if it doesnt air lock then your good to go.

wow nice design... you did it yourself? very interesting.

So it is safe to pump CO2 into the canister... btw how do you find out if the canister is air locked?

[imi_sky]

they should tell u on the packaging most of the time, or check online to see its specs. if you cant find it then try e-mailing or get in contact with the makers support.

The reactor is attached to the outflow from the canister, not the intake. It is only on the intake that air may build up and cause it to lock.

I see. I was asking about the locking effect as I was thinking about pumping the CO2 into the canister from the inflow, until Dom from the above thread said that it might kill of the bacterials.

[retardo]

The reactor works best on the outflow. The CO2 goes through the reactor on the outflow and out to your tank, where it is immediately available for plant consumption. When it is on the intake, undissolved CO2 has a chance to accumulate inside the canister and cause the lock.

Also, CO2 in the water column does not displace O2, except in high concentrations. O2 will still be available for the bacteria inside the canister or other areas where they may be living.

ic thanks for your info. Will be changing the set up of my CO2 soon. :)
