Recirculating Co2 Scrubber cap for Red Sea Reefer DC 350

[SopmodSnapper]

Tank is 6 months old and constantly having issues with pH sitting at 7.8. Looking for recirculating Co2 Scrubber cap that fits a Red Sea Reefer DC 350 skimmer. It is the one with the wire and sensor that installs down the middle of the cap, used to auto level skimmate. Looking for something simple, possibly 3d printed if something like that exists. Any help would be great. This is my first post, so thanks in advance.

Pretty sure there's a guy at fishofhex that 3D prints these. Name is Travis as I recall.

I bought one from fish-o-hex and it worked great BUT two things; you need to be careful bc once the skimmer cup overflows, it gets into the CO2 scrubber and more importantly, it raises the sensor just enough that the sensor does not turn down the skimmer when it is overskimming. Maybe he could print something to overtop the skimmer cup instead of a ring that fits on the cup between the cup and slimmer lid).
