I like hearing those words in talks of filtration, quality COARSE materials, that allows a continual and even free flow through, making the media perform to its very best, the coarse material to,, my preference to coarse is matalla mat or the likes of.
I see to often, people's set ups having their biological parts of the filter effected greatly by the mechanical part, either effected by lack of water flow or blocking of waiste,,,,,, and this can be occurring three quarters of the time between filter cleans.
Lots of disease can arise from this.
