No, they won't honor it.I bought my RODI from Marine Depot because they had a deal that so long as you purchased the unit from them, you got 15% off of the replacement filters, etc. for life. It was a nice deal. They also had amazing service when one of the elbows broke. I'll miss them as a vendor. I wonder of @Bulk Reef Supply will honor that program?
I too bought a MD Kleanwater RODI system, so I contacted BRS customer service and they told me (in writing) that they will not honor the 15% off for life filter replacement. Time to stock up before July 30th...
