Red Sea Reefer Aquarium Replacement Return Connector 16mm R42221

I used this to pvc hard plumb my reefer 250, by taking out the barb and putting in a MPTxslip adapter in its place. I'm very thankful Reefsupplies.ca carries this!

I used these fittings to replace my Red Sea nano stock sump with an Eshopps nano refugium dual channel (patent pending) sump, which fits perfectly in the cabinet, but allows for use of a refugium and a protein skimmer simultaneously and maximizes the use of the space available. If you plan on customizing your plumbing you will need these fittings.
