man I love going against the grain :)
Slowly, over the course of the last few years, I have more and more moved to mechanical filtration and rely very little on biological and chemical filtration. My understand has always been that the surfaces in the aquarium hold far more beneficial bacteria than the filters themselves. Not that I dont use biological filtration, I just dont use it or rely on it heavily.
on my fry tank I straight use a box filter with some filter floss. No issues.
my 55g has one tetra HOB (no bio at all, except for the mech pad) and a penguin biowheel 200.
my 20g ram tank has an aqua clear 20 filter on it, with just the included few ceramic cylinders.
my 110g has 2 dual tetra HOBs on it, and then my ecco 2236 has the bio media.
I usually just swap filter pads when they can no longer be swished clean, and I dont typically experience ammonia spikes or mini cycles, though I also dont do water changes, gravel vacs, and filter pad changes at the same time.
Im wondering if he could just find a spot in the filter for a bag of biomedia, aqua clear style?
