I think this is the last thing I have left from my aquarium. I am selling my RO/DI unit. I have a spare carbon filter and the RO filter should be good, but the micron and DI resin should be changed. Pressure gauge doesn't work quite right. Unit is a Triton filter by Hydrologic. Posting from my phone so no pics here but I can send pictures if needed. Text at 858-603-9720. Looking to get $40 open to offers
