Dukes, thank you, you should give it a try it's not that difficult.
888, thanks, that's a lucky number!
hawk, here is a picture of an inflow that I made, the end is a little bit rounded but I didn't worry about it a lot because I was planning on putting a sponge over the intake to keep shrimp from being sucked up. I plugged the end by gluing in a short piece of the solid acrylic rod that just happens to fit pretty tight.
A drop checker, I'll have to think on that one for a bit.
