I really, really appreciate that you do all the DIY stuff -- your Maxijet mod is WAY cooler than just buying Tunzes. I have a retired (but still working strong) Maxijet that I'm going to do your mod on. Not because I need it, but because, like these skimmers, it interests me. I want to build a DIY internal wood airstone skimmer as well for my 20g hex -- I just know I can improve on the Lee's downdraft that's in the tank already, it's such a pain to clean!
I'll probably be putting the CS-180 on my forthcoming 75g lionfish tank. I enjoy watching it work too much to let it go -- I watch the thing work more than I watch the fish in the tank it's so sad.
This forum would be better if everyone just contributed in a positive fashion as you do, keep it up...
