Carbon Doser Replacement Gauges don’t exist?

[Asonitez]

Is it me or is there no place to buy carbon Doser replacement gauges? For a 300 dollar piece of equipment the gauges rust easily and while I understand everything breaks down over time I’d like to find some replacement gauges for my carbon Doser. One needle seems stuck (pressure psi needle) but the other works fine (bubble size.)

Any tips would be helpful.
I’ve mailed aquarium plants numerous times and got no answers.

You can get replacement gouges from an industrial supply house, welding supply and lots of other places. I think most we be better quality. Just take your old one to a local supply house. Let them know it is for CO2.
