I was wondering whether there was a downside to having too much mechanical filtration......as the "filter floss" gets full of gunk, will the water quality go down as it continues to pass through that gunk? Will the collected gunk start to add to the ammonia/nitrate/nitrate/phosphate levels in the tank as the water passes through it over time? Consider a canister filter such as the large ViaAqua, and putting filter floss in all three baskets, and not changing that floss until water flow starts to noticeably diminish.....this may be 2 or 3 months.....
