Help! Gluing Pipe to Reactor Body

[straightrazorguy]

I have a Vertex RX-C 6D calcium reactor. Today, while cleaning it, the bottom pipe attaching the pump to the reactor body came apart. The pipe isvred (PVC, I think) and the reactor body is clear acrylic, I think. What do I use to glue the two together? I don't want the tank to be without reactor for too long...
