Me? How did I mount my hydor? I actually got it today and put in on this afternoon. Here's how:
1) On the display side of the false wall, pull the deflector off
2) The pipe with the "bulb"(good discription, I couldn't think of what to call it) comes off too, so pull that off
3) What you should have is a pipe that is built into the false wall, and the third largest hydor adapter fits that end
4) Put the hydor on the end of the adapter
I found out that the bulb end piece came off when I took the deflector off to wipe it off and the whole thing came with it! I thought I had broken it :lol:
Good luck
