Filter media

there is this sudden craze about K1 media, which claims that the media's constant chaotic movement within the filter causes the old dead bacteria on the outside to be displaced. This makes space for new younger heavier feeding bacteria to rapidly colonize. What is your opinion on this claim?

How does the friction caused by the knocking of media only remove the "dead" bacteria? If so, why does the outer layer always remain clean compared to the inner surface area?

What is the natural lifespan of beneficial bacteria?

How can we tell the difference between young, old, strong, weak & dead bacteria?

When filter media becomes darker in color, are those Bio-film or sludge? How can we tell?


- Taking into consideration the tropical climate in Singapore, where fishes eat more, what is the ideal system for tanks with high bio-load?
