Hey. I just got your comment about the filtration in my 10 gallon divided. I'm using the filter which came with the tank which is a filter for 5-15 gallon tanks. I put the intake in the middle section and the output is resting on the left section. I'm using a piece of aquarium sponge rubber banded around the filter for a baffle. If you don't care about the filter current though you can use the water bottle method.
