Hi, I am new to Reefing after 11 years of freshwater. I got myself a Reefer 250 to start with. The return pump I ordered (Sicce Syncra Silent 4.0) did not come with the 5/8" adaptor for the return line the sump came with. I thought it did but that was my fault. I have no plumbing skills . What adaptor can I buy online to use this pump with the Red Sea return line? With this whole quarantine going on online is my only option at the moment.
