    I busted my Hagen Ladder for my DIY co2. I have no money to spend on anything new, nothing at all... not even a dollar really. Pretty much most of my co2 is coming out of the tube & straight to the surface, skipping the ladder entirely. (I broke off the bottom suction cup & cant get it to stick flat on the side of the tank.) Is the best of the bad options going to be blowing the cos thru my filter, or is there a better way?

    Also, is there a qay to calculate the amt of co2 in my water? Or is that another test kit all together? I seem to remember seeing someone talk about using kh & Ph to determine it...

    thanks

    Thats the stuff! Thanks alot Paul.

    What would be better to use? A wood airstone, or a regular airstone? Just saw the two at my LFS & didnt know if one was better than the other.

    Re: Co2 questions

    You need the co2 to have prolonged contact with the water. An inverted bowl at the bottom of the tank propped up on some rocks so that a bubble of CO2 can accumulate under the bowl. Then take a powerhead or the output from your canister and create a flow of water beneath the bowl. This will allow the water passing below the bubble in the bowl to absorb the co2 as it passes. The co2 tube should be tucked up inside the bowl so that the co2 bubble rises and gets trapped into the bowl. This method works well on small tanks.

    Simply feed the COI2 into the intake of power head and point the flow downward.
    Plug the powerhead into the lighting timer.
    Better than the ladder.
    Add the DIY reactor to this later.

    Do you think the c02 would be better into the powerhead than into a JBL de-fusser??
    I might try your powerhead de-fusser when I find another spare socket.... :)
