I am setting up a SW tank, and using my old equipment. when setting up the MP20 powerhead, the propeller tries to work, but will not. Do I need to order a new wet side for my old MP20? Thanks :help:
Got my dry rock from reef cleaners, and WOW!! really nice rock, and 30# looks more like 50# of live rock. Beautiful pieces. Will post pics when they are in the tank
