You broke the stub off that is welded into the PVC on the cup. That black elbow is a Metric John Guest fitting. What I would do is get a thick paperclip and bend the tip so it’s hooked shaped. Push the hook into the John Guest Fitting on the side that the broken stub is still in. Push it past the end of the broken tube and hook the tube. Push the collar on the John Guest fitting in while pulling out of the paper clip and you should be able to pull the broken tube out. Then clean the end of the broken tube with some rubbing alcohol. Do the same on the broken end on the bottom of the collection cup being careful not to get it on the acrylic. Glue the stub back in place using some Ca and then add a thin layer of epoxy into the depression in the bottom of the collection cup being careful not to get it up onto the tube. The idea of the epoxy is to fill the depression up high enough that it covers where the crack was. Let the epoxy set and dry and then slip the John Guest fitting back over the stub.

If you were to buy a new tube, you would need to drill out the original stub perfectly and then use PVC cement to glue the new piece in place. That is always an option if the suggestion above doesn’t work.

Regarding the lights, those were the old Reef Tech’s.. I remember those lights well. LOL
