Replacement UV Tube and Gasket for Fish Mate 2000, 3000 PUV and 3000 PBIO Filters

UV tubes fade across a season even though they still light, which is why green water returns in a filter that looks like it is working perfectly. Fit a new tube each spring. This one covers the Fish Mate 2000 and 3000 PUV, references 266 and 267, and the 3000 PBIO, reference 271.
