Also true, if you look at pretty much all good light, dosed tanks that have the wow factor clean water via the water change is pretty much standard practice. I think the WC is overlooked more with a ADA since it's a complete system and just one think that is needed. The dedication to the tank is still key and it's not a self-sufficient system as "some" continue to preach.
