Good point! It is much easier to clean the larger pieces of substrate in a FW tank, than the sand substrate most of us use in our SW systems. Im my 2 larger tanks, I have a lot of critters living in my sand bed I do not wish to disturb, which are detrious eaters & should help with that problem (both tanks have DSB). In my nano, I have larger grains & I do stir the substrate with a chopstick before each WC.
When I kept puffers in a 55g I used crushed coral & while doing my 50% weekly WC on them, I'd use the gravel cleaner with a Python to clean under & around all decor.
