I have a Digital Aquatics Reef Keeper Lite for sale. I'm traveling out of town this week however will be back next week and can meet and / or ship at that time. This controller comes with the following modules.
2 / Ea PC-4 Modules
1/ Ea SL-1 module
1 / EA display module
1 / Ea Ph Probe
1 / EA iTemp probe
All requried mod bus cables
All required mounting screws
Asking $200 however will entertain any reasonable offers.
The only thing I think I don't have is the necessary pH calibration solution but I'll check. It's possible that I have some. LMK if interested. PM is key.
