No, but you don’t need an actual second co2 scrubber, just need a jar or something to run the line from the skimmer into and then a second line out and to the scrubber so any excess moisure is trapped in the bottom of the catch container. Just make sure it’s a tight seal around the lines so it’s not leaking any outside air in.Wait so i have to another scrubber just for moisture this is getting expensive man. The co2 scrubber i bougjt have a valvr for bleeding in case high ph. Wouldnt that help with moisture
