    There are many CO2 delivery system in the market. Which do you use?
    How do you think about its performance? Would you recommend it?

    I use inline diffuser because it is one less item in the tank so less clutter... and it doesn't get algae so easily (since its hidden away from light), so less cleaning required.

    Do you put it at the inlet pipe or outlet pipe?

    I have and i use all 4.
    My favourite is the reactor.

    And also a CO2 "circulator". which i used once only.

    I install mine at the output hose, as per recommended placement.

    I've seen friends put them on the input hose though, hoping to get the Co2 mixed and diffused even more by tumbling through the canister filter sponges and media... looks like it could work too, but the risk is gas cavitation building up inside the canister and causing the impeller to run with less water. I guess that probably could happen if there is high bps rate being pumped in for long periods of time.

    Eric, how many tanks you have? haha. By the way what is a CO2 circulator.

    Hi Bennyc,
    I know you are not talking to me, but i thought i should share my experience with you.

    I have placed the ISTA reactor and UP inline atomizer at both inlet and outlet.

    the inline atomizer in the inlet side was a mess. The pump was very loud, most probably due to accumulation of Co2 in the filter.

    the ISTA reactor had the same issue, but somewhat lower amount of noise. Which indicates to me that less air pockets were formed. I had better control over the CO2 with the ISTA then the inline atomizer.

    Therefore i recommend that if you were to get the inline atomizer or reactor, connect it to the outlet. I understand that changes water pressure can cause dissolved air to "un-dissolve". when water exists the pipe into the media column, the pressure of the water might drop, causing air pockets to form. Same thing when the water is pushed out of the outlet pipe into the tank.

    Re: Which Co2 Delivery system are you using

    Thanks eric, for sharing.

    I am starting this poll to have a gauge on what everybody is using. Another thing i was hoping to achieve is that people will share their experiences using different product to benefit people like me to have an informed decision to "jump ship" to another product.

    Re: Which Co2 Delivery system are you using

    I've used them all before, and highly prefer inline diffusers. I think reactors dissolving CO2 into the water is not as effective as "misting" via diffusers/atomizers. Between atomizers and glass diffusers, I would choose atomizers as they are smaller and less conspicuous in the tank. However, inline diffuers win for me because they are outside of the tank, require less cleaning and are convenient (just install and forget for a long time).

    In my nano now, I'm currently using an atomizer as an interim measure, since my ISTA inline diffuser sprung a leak and I'm waiting for my UP inline diffuser to be delivered from Taobao.

    Re: Which Co2 Delivery system are you using

    It seems like inline diffusers are a very very popular choice. But, it requires a 40psi right? all across the brands?

    nope. only ones that can deliver mist need 36-40 psi range.

    there are different brand of inline diffuser. Boyu and ISTA does not require high pressure but cannot create mist.

    Sorry Felix, i am not very familar with inline diffusers. So UP needs 36-40? what other brands need 36-40?

    I am not good at psi, so does it mean that when the CO2 is close to empty, the inline will not work? wasting the little CO2 left.

    Re: Which Co2 Delivery system are you using

    If you are using regulator, you will see 2 pressure gauge. One for tank pressure which normally will show 1000 psi, the other one for working pressure which normally will show around 20-25 psi. To use up inline diffuser, you need the working pressure around 36-40 psi instead of 20-25 psi.

    In other word, you cannot use up inline diffuser if your regulator can only output 20-25 psi.

    Shadow,thanks for the explaination. A follow up question. The working psi is not affect by the amount of CO2 in the cylinder?

    Is this considered an inline diffuser?
