I am setting up a 210 (4ft x 3ft x 27 1/2 in) and it is a sump tank. i have other large tanks and run them with power head and sponge filters. i baught this tank new so i could learn how to do a sump. i have a 40 gallon to be the sump tank and would like some ideas on how to do a cost effective sump set up.
thanks
