| what is the best mechanical filter media?
Regarding our discussion about mechanical filter, I need your opinion about mechanical filter media comparison.
my first filter is vortex but unfortunately debris still go to next chambers (bioball).
Recently I moved bioball in chamber after vortex and hoping it would settle the debris but not.
I plan to use brush in that chamber,the other still using bioballs. what do you think?
which one you thing better, brush or japmat for mechanical filter instead of biological filter?
