I have a concern ...
My 40 gallon tank with semi aggressive ( what i call community tank) has an over the back filter strong enough to use alone. It is a mechanical and biological filter combined.
i choose to add with this an under gravel filter with power heads.A great biological filter.
I think they increase the oxygen flow and kep my tank water clearer.
Despite all the negative things you hear about them i never had a problem with it on any of my tanks. My question is this...
Should I or Can I add some kind of substrate to the bottom of the under gravel filter so it can also help in its filtering procedures?
is it mandatory?
does it change anything?
would it be beneficial to my tank?
should i at this point not disrupt it to change it?
i am moving at the end of the month locally but still moving if i had to add the substrate i feel this is the best time to do so
can some one please see my need for advice that the professions cant give me?
