My new system is going to have a 40 gal prop tank.... the return from the main tank will run through it and I have set it up with a bunch of baffles in a zig zag pattern about 6" apart so that the water has to flow past every frag. This should allow me to have great water flow without the need for a bunch of pumps
My return pump is a mag 18 so there should be quite a bit of flow.....
I am building a new house with a large bonus room that will house my new tank set up (225gal)
I will be building a tall cabinet right beside it to house the sump, the prop tank and my fuge. So everything will be self contained in one area. I will be running a 250W mh on the prop tank....
