i wanna try my wood working skills and build a ply tank. i wanna try smaller at first then ill try a bigger tank later. i was thinking around a 40-60 gallon would be decent size. i want to do a sump system also. i havent had a sump system before. does anyone have some sort of diagram to help me understand how to put a simple one together. also what kind of GPH would anyone recommend. thanks for the help and i plan on starting this little project one the first of the month. thanks guys
