caferacermike said:Franklin could you give a little better idea of what you are looking for?
IE: Is this just a sump to add water volume? Do you want wet/dry? bubble traps? is a skimmer going in there, if so how big? Do you have a fuge or are you planning on the sump being part of it?
If it's just for adding a skimmer and some water volume a 20g tank works well with a few dividers siliconed in place.
