finkids make me happy :-)
by looking at your intake for your hob filter, it seems you have one of those Marina slim filters. IMO, not good filters at all. they take cartridges, which are a joke, and there is no easy way to modify this style of cartridge filter for using a sponge in it instead (because the filter box is so darn narrow).
i tried to mod a friend's slim 15 with just one piece of sponge in the middle compartment and a cartridge in the other ones and nearly had an oveflow out the back of the filter due to the backup of flow against the sponge. used a piece of Aquaclear hob sponge, cut to size.
