LiterMeter III, WXM, RPM, TCM - Brand new

I ordered the complete LiterMeter system for continuous water changes and auto-top offs. I didn't realize that I already had the capability to do all this with my existing spectrapure pumps and Apex. These are brand new and I just received the shipment yesterday - 11/7/16. Unopened. Spectrapure charges a 20% restocking fee. So my loss is your gain.

Here are the list prices:
LiterMeter® III LM3-115 - $279.99
LiterMeter® III Overflow Protection Module - Gen6 - LM3-TCM-G6 - $49.99
LiterMeter® III Water Exchange Module - LM3-WXM - $149.99
LiterMeter® III Remote Pump Module - LM3-RPM - $119.99

I will sell each component for 15% off what I paid, including shipping.
LiterMeter® III LM3-115 - $238
LiterMeter® III Overflow Protection Module - Gen6 - LM3-TCM-G6 - $42.50
LiterMeter® III Water Exchange Module - LM3-WXM - $127.50
LiterMeter® III Remote Pump Module - LM3-RPM - $102

The whole system for $500, or each piece separately.
