im thinking of building a 200gal tank and filtration system. while im pretty handy and dont think i will have much of a problem. i was wondering how much water would be good to continiously run through it.I have two 55 gal. tanks and a 30 gal. tank available. I was planning on making a sump pump filtration system and was wondering if it would be better to use two pumps.Basically,would it be better to use one filtration system or two?
