Stop Overfiltering Your Aquarium - Why Too Much Filtration Stresses Fish and Destabilises Tanks

This episode takes a deep but practical look at overfiltering in freshwater aquariums and explains why more filtration isn’t always better for fish health or long-term stability. Many hobbyists unknowingly create stressed, fragile systems by using excessive flow, oversized filters, or overly aggressive mechanical filtration.

You’ll learn how filtration affects fish behaviour, beneficial bacteria, and planted tanks, along with clear signs your aquarium may be overfiltered and how to fix it without sacrificing water quality. If your tank looks clean but never feels stable, this episode will help you rethink filtration from the fish’s point of view.
