Hi all, just like to seek some opinions on whether I should use 2 sets of Ehiem 2075 with one connected to external CO2 reactor and the other connected to a chiller or simple 1 x 2080 connecting to both co2 reactor and then arctica chiller? which will give a better flow and will connecting to different filters results in uneven distributions of cool waters and co2 rich waters as compared to just one?
