    hi all, i'm irsan from indonesia. first of all let me say thank you mr barr, i'm a big fan of this forum, it really helped me a lot.

    recently i put a lot of my time reading about co2 and i eventually bumped into two stages regulator topic, and i can see that everyone cmiiw here is using two stages regulator. fyi for all this time i use the cheaper regulator like the one from UP or ISTA, its very popular here. and yes the co2 rate slows down along with the depletion of the gas, so i would have to adjust every week or so. its very hard to find any two stages regulator here, and it surely cost a lot. so my question is, does the two stages regulator really worth the $ and all the troubles that would cost me to get it sent here? what could i really expect from a two stages reg? what is the direct impact to lets say the algae in my tank?

    Hi irsan and welcome,

    Can you provide a bit more details on your tank setup and algae?

    Generally, with c02 it is usually that:

    a. You are providing INSUFFICIENT c02 for the LIGHT PROVIDED and/or bio-mass. More light uses more c02.

    b. You are providing UNSTABLE amounts of c02. Not enough at mid-day for example.

    c. A AND B :)

    Your requlator and other hardware will ASSIST with these things but it is really only at the end of the tank that it is more of a concern with the single stage regulator.

    A better quality needle valve to regulate the c02 rate and/or a more efficient diffusion method for your tank may be a better investment initially.

    Hope this helps.
