This may seem a bit off-topic, but actually not given the number of breeders on this list. For sponge filters, does anyone have comments on the HydroSponge line? I'm trying to compare those with the homemade-looking cube-shaped 4X4X4 filters with a ceramic tile on the bottom and PVC tube sticking out of the top. Both types are available, but I wanted some seasoned expert opinions (that's you guys). I would be using these both with and without substrate in different tanks for breeding and (hopefully) grow-out.
