So I had this idea to setup a mini sump that was removable, making water changes way easier (nothing against the bucket method). I didn't want to drill the tank because I hate how it looks without the false wall. I also am a cheapo.

So I set out on a journey to build everything from things I could get at Walmart and Canadian Tire. The sump box was easy, a bathroom garbage can (albeit I had to get a second one because I failed to check for holes in the first one. When trying to contain water holes are not your friend) The overflow was the difficult part. I know the basic concept of siphon (helluva way to get free gas), but the 5 mins of looking on the internet lead me to a huge ugly PVC overflow. no dice I like clean looking tanks. So using nine 1/2 inch PVC elbows and two tees (T's) I came up with this:

Priming it is super easy. I just hold it at a certain angle and dunk it in my tank. then i plug the intakes with my fingers until its in place. it supplies 26-30 GPH but I think I could double that by adding a second drain pipe. I'm creating detailed plans for this and other larger capacity HOB overflows, if anyone is interested.
