I'm going to set up a 50 gallon AGA (36x18x18) reef tank soon. I already have the tank and stand. It's the usual AGA pine stand, so there isn't a ton of room under there. I know I want to go as big as possible so I was thinking about using a 29 gal DIY sump, if it will fit, otherwise I'll use a 20 long. I'm really interested in seeing plans and photos of others' DIY sumps because I'm just having problems visualizing how it's all set up- I'm really not that great at DIY but there's no way I'm shelling out the cash for a premade sump.:silly: So show off your pics, please!
