Hi every1 Currently im having a spio diffusor for co2 in my 260 liter. I want to add abit more flow to the tank, and was thinking on trying and buying a cheap chinese plactic reactor. Something like this: http://aqmagic.com/store/product_info.p ... er-reactor Thinking on an Eheim powerhead on 1000 l/h or so to pull it. This would satisfy my need for flow. Does any1 have experience with these reactors. Thinking on diffusion rate and how big a tank, they would be capable of supplying.
