Most people like to have a minimum of 20-25% of tank volume for sumps. You can vary this however you see fit. Just amke sure that you have enough "Extra" room to account for any power outages.
does anyone have a good drawing of the setup. like how low to put the intake into the tank, and where to put the pipe back in? sump set up, and type of sump?
