Need help with PM 622 calcium reactor. Every few days feed pump (maxijet 1200) stalls and CO2 builds up in reactor dissolving media in reactor without dripping into tank. The only way effluent starts again is if I increase the effluent flow but then my Ph drops to fast. Not sure if the powerhead is being stalled by too much back pressure from having to push through reduced tubing sizing and push through media of 2 chambers or what.
