    I thought I saw it at GC...it looks like a regular diffuser encase in another glass bubble...

    How is this better than the regular diffuser?

    Normally, people are talking about this model.


    David, you are very High Class. Show the Calaqualab model. Anyway, they have a offical distributor at Bangkok JJ market. Wanted to go visit the last time i went Bangkok but no time, so wasted.

    Re: Which Co2 Delivery system are you using

    No Lah Bennyc ...I my belief is have a nice tank that looks good... Just looking at it makes me happy. I go for looks first price later. If out of my reach, I rather save the money for it than to go for the next in line.

    It's just me ...I guess...

    So I cannot get this in Singapore?

    Working pressure will not be effected as long as there are still liquid CO2 in the tank. As long as there is liquid CO2, the tank pressure will be around 1000psi. Normally you will notice fluctuation when the tank pressure drop below 400psi (estimate, I do not know the exact)

    Do note when you psi show 500, it does not mean your tank half full. Anything below 800-900psi means empty. You can only tell the amount of CO2 in the tank by weight not pressure.

    I am not sure if this is just marketing talk, but i sort of believe it.

    The reason why its betterr
    in normal ceramic diffusers, the CO2 is forced into a fine mist by pores on the ceramic plate. This CO2 is small and gets dissolved into the water easily. To further aid the process, some people (like myself) like to point the outlet of the filter towards the ceramic diffuser. It disrupts the CO2 stream, causing it to whirl around before going straight up to the water surface.

    this design does something similar, it creates a flow of water surrounding the CO2 stream. promising a higher rate of dissolution or finer misting (i am not sure).

    Thats my take..

    Re: Which Co2 Delivery system are you using

    I am using the below setup for CO2 reactor (Ista Mixer):
    Attachment 36906

    connected to my basic and simple bubble counter:
    Attachment 36907

    and finally connected to my CO2 cylinder with ANS eletric soleniod:
    Attachment 36908

    IMHO, the aim is actually to get CO2 effectively mixed into the water in order to prevent wastage of CO2 that normally floats onto the surface and in turn provide for the plants. I feel that the Ista mixer is pretty good as you can see in the below video, there is hardly any CO2 bubbles visible that is discarded from the mixer:

    Re: Which Co2 Delivery system are you using

    For me, I chose to use ceramic diffuser as I like to look at the bubbles that are released into the tank. My diffuser is placed directly under the outlet lily pipe to ensure the CO2 bubbles can be push around the tank. The diffuser is also placed at the back of the tank.

    Re: Which Co2 Delivery system are you using

    Hi Eric,
    How many bubbles / sec is that?
    I have about 0.5 bps for my 3 ft.

    I was advised to go with 2bubbles per second for a start.

    that very little for 3ft, I use 6-8 bps for my 3ft but again it depend on how much light you put on top.

    Agree its very little! I don't have a lot of light on that tank and the plants are not demanding.

    Re: Which Co2 Delivery system are you using

    Yeah, the number of bps for a tank is very subjective... it depends on the bubble counter, efficiency of the diffuser, size of the tank and the plant density/requirements, there is no fixed number of bps as everyone's equipment and tank conditions are different.

    A tank with low density of plants during the initial grow-out period takes in and process less Co2 than in a matured tank with very high density of plants, so have to monitor and adjust accordingly over time.

    Most importantly is the drop checker shows green color, and the fishes/shrimps are not gasping for air or dropping dead.

    Point to note is if you do a heavy plant trimming and remove say 50% of the plant density, its a good idea to also reduce the Co2 to match the reduced intake too, that's one of the reasons why some people suddenly find their fishes and shrimps dying from excess Co2 after doing massive trims.

    Re: Which Co2 Delivery system are you using

    I am using ISTA Turbo CO2 Reactor Diffuser. I found it helps to dissolve the CO2 better into the water and the plants start pearling very well.. Also I try to reduce the CO2 rate and it still works well.. save my CO2 too.. :-).. Bought $18

    This type confirm must attach prominently outside the tank to show people... most of us use the cheaper plastic "workhorse" ones though, which are relegated to stay hidden inside the cabinet instead.

    The one with 2 ceramic tubes 100% need higher then 36 PSI. The other one with 1 tube i believe people with 25PSI were able to use it. (double check with wongce on his working pressure)
    Inline ones in general need higher PSI.

    I've used a cheapo $3.50 diffuser before, it was as good as glass diffuser maybe better

    Short note, if your using the splitter it goes down even more!

    This is a very good point, i've previously used the ISTA inline (that i do not know how i managed to crack it anyway) and i see zero bubbles going into tank and drop checker green until morning 7.30AM (lights off at 12MN)

    how i hooked things up (Orthodox method, flowrate will drop like MAD)
    Tank->Canister->Inline->Prefilter->Tank
    I've also known a certain member whom is no longer active, made a reactor from a small glass tank & glass diffuser (IMHO works better then reactor since reactor mostly co2 going in is bigger bubbles)

    Re: Which Co2 Delivery system are you using

    just check out wongce's blog, he actually did a review on the UP Aqua Inline SUPER Diffuser. it is a two tube ceramic inline diffuser.



    I don't own the picture, it is wongce's. (Wongce bro, where are you, share some expertise here, please)

    He mentioned that it needs a working psi of at least 35.

    Re: Which Co2 Delivery system are you using

    felix,

    I do not understand your rationale, Tank->Canister->Inline->Prefilter->Tank.

    why is the prefilter last? Should not it be Tank->Prefilter->Canister->Inline->Tank.
