Hello All! First post here. I’m currently using a korallin c4002 with an ecotech versa pulling water through the reactor. This seems to be a recipe for pressure lock (can’t get CO2 into reactor without higher pressure). I think that the korallin reactor was designed to not require a feed pump in any fashion (It pulls water Into the reactor at the same rate it returns water) by putting the peristaltic pump after the output I’m just creating back pressure. I’ve decided to replace the versa (after designated reactor output) with a needle valve turned down to a relatively slow drip and use the versa to pull an accurate rate through the alternate output located directly on top of the reactor ( I think this is an excess CO2 valve). I think I just need some thoughts on this. Anyone tried it?
