So once we move we are going to be setting up two 75G tanks we are going to get soon from a member and for filtration I want to do a sump. The two tanks already have drilled overflows in them so I figured why not do a sump. One tank will most likely be housing my cats for now and the other we havent decided on yet. I have two layouts that I will attach, I like the first but need opinions. The first consists of stacking containers with large hole cut out of them with a mesh type cover. First container will contain filter floss for easy removal and cleaning to catch the bigger stuff, second will be the sponge, the next two or three will contain some sort of media. Not sure on what media to use so I would appreciate suggestions. The second layout include floss at the overflow sitting on an eggcrate or something, then between the first two baffles will be the sponge, then through another baffle past the heaters, then into the media chamber including some type of media (again suggestions are welcome) maybe bio balls, then the next chamber will have substrate and some plants to remove nitrate, Then to the pump and out. I was going to use 1" pvc throughout, Is this big enough? Since ill be running two tanks from one sump Ill have to split the return line. I only want to use one pump, I was thinking about getting the Rio Plus 2500 as its rated at 782 gph after head travel i think it will be around 500-600? As for the line splitting I was just going to use a T. If anyone has a better way of splitting feel free to share. Right now this is just the planning stage, I'm open to all suggestions. I appreciate all input, Thank you.
