Hello everyone. I have a quick question for you all. I recently started back up with a 29 gallon Biocube reef tank. I have an RODI unit that I used with my previous tank. I am wondering if I can start reusing it like I never left off or if I need to replace all of the filters. They have been sitting indoors in a controlled room temperature for about 6 months with nothing running through them over this time. The filters currently in the unit have not been used much. Thanks!
