Does any one know how to make a DIY sump?? Also what are the pros and cons about them??

au01st

I'm making mine out of a 20gallon long tank. Pros: cheaper, you decide the size of the chambers. Con: have to DIY.

I traded some other stuff I had sitting around for my 20Long tank, so that's cheap. I will probably spend $30 getting acrylic cut, and maybe another $20 on glue (BTW, does anyone know what bonds acrylic to glass?) and that's it. I can decide where I want my inlet, how big each chamber should be, how high the baffles will be, etc.

Are overflows better than drilling a hole in the tank??

au01st

Yes. If your tank didn't come with pre-drilled holes, the overflow will be better. It won't compromise the glass, you don't risk breaking it, and the one I'm looking at that flows 800gph only costs $40 on DFS. It's "Eshopps" (sp?), and they have a smaller one, as well as larger ones.
