Precision Marine Calcium CO2 reactor tank regulator contact chambers pump

Description

Precision Marine Calcium  reactor
used on a 240 gallon marine tank. Everything was working when the tank was taken  down. There should be 2  PH probes but i only have 1,  it should be changed anyway since its old. The computer to control the unit is sold. It can be operated manually but a controller is required for more precise control. The  o-rings should be changed too just to be safe. The CO2 tank will need to be recertified.
Im selliing this for someone else and told it was complete . I tested the pump (with water,, no dry run) and co2 solenoid and both work. It would help if you had a good understanding as to how these work since there is no owners manual. It looks  the hose fitting on top of the CO2 bubbler may be broke off and will need to be replaced.. Theres spare parts and PH calibration test solutions.
