you don't understand what I am saying i guess. co2 in water is acidic which will in turn lower your ph at least some. it has to it's just the way it works. co2 is also needed for algea growth. I am not saying it will be a sole cause or that it will even cause a problem for sure but it can. why not do something to prevent it before it happens is my way of thinking. not that I always follow my own advice like an idiot. you won't find much info about it because in all honesty most people in the hobby don't understand the effects of co2 when mixed with water. I wouldn't know it unless i had trouble with it myself.
the geo and honestly all other reactors that do not recycle the co2 are marginal at best. maybe geo has copied now but I just haven't seen it. if you look at a shuran it is a pretty easy modification to make when your in the building process. I owned a geo and so did several people I know very well and we all had trouble with them for one design flaw or another.
where do you plan to regulate the effluent? this is another issue with geo reactors last time I saw one. hopefully he has changed it since I last saw one.
not trying to say my way or someone else's way is the only way I am just trying to help you not make the same mistakes I made along with many others.
