Above-tank mounted sump design

There are few things that can benefit an aquarium, particularly a salt water aquarium, as much as a good sump. Sumps allow you to create an entire system separate from the main tank that contains all your water processing, heating, conditioning and so on without crowding or visually afflicting the main tank; they allow you to add chemicals and treatments to the water and have them pre-mixed with a large volume of water before they reach your aquarium’s inhabitants, and much more.

But traditional sumps require expensive main tanks with plumbing ports (you can’t add ports to your typical large, inexpensive aquarium, as they are inevitably built with tempered glass), and are mounted underneath the main aquarium where they require bending over to service. Both of these issues go away with this design. You can use any non-ported aquarium as your main tank, so that $500, 75-gallon aquarium with stand from Petsmart you’ve been eying is just fine, and the sump is above the tank, perhaps on a floor above, where you can actually get at it and maintain it.

Here’s my design. You are most welcome to use it.

Python, TkInter, OSX (OS X) and making it all behave

I use Python a lot. Python 2.5.1 to be specific. And inside Python is TkInter, which, with a little work, will give you a handy way to put a GUI together. But there are problems. To say that TkInter is poorly supported and poorly documented under OSX is to understate the case rather dramatically. So you’re left to Google for answers, and mostly, they aren’t to be found — or if they are, they aren’t obvious or easily found. So I’m going to provide some answers here that have taken me quite some time to collect, and hopefully keyword and title them so that a Google search will actually get you to the solution you need sooner rather than as much later as it did me!
