After a 35-50% pwc on my Fluval Spec 5 gallon aquarium that has nearly perfect water parameters per API Master Tester kit the substrate is still filthy if its disturbed even a tiny bit. I gravel vacuum every time which is why 10-20% only water change is nearly impossible.The siphon empties the tank way too quickly. Twice since getting the Fluval I have done 100% water changes still w/nothing but 2 medium Mystery/Apple snails in the tank gravel stays dirty.
