Power Filter Question -Bio Wheel VS Bio Bag2007-11-24 23:40:10

What is the different between bio-wheel and bio-bag? Do they have the same function which keep the good bacteria? Is Tetra Whisper Power Filter is the best choice?

Answers:

Okay. Let's keep this simple. bacteria grows on the surface of the Wheel, Bag etc. (Whatever host material). Therefore, the BEST material to use is one with the BIGGEST Surface area. This will provide MORE bacteria to live on it. Thus, choose one with the largest surface area. Simple?

Power filter (Or whatever filter) is good only if it can turn around enough water. This means have the water in the tank going thruogh the filter. U need to have at least 3x the water tank capacity in order to have a good filter system. U can go up to 5x the water capacity, provide your fish is okay with the water current flow.

I am not familiar with a "Bio-Bag", but if what you mean is a Canister Filter (like a Fluval) then the answer to your question is yes - they both retain the good bacteria, but in a much different way.

I use Marineland's Emperor 400 (have 2 of them on my 90g All-Glass Aquarium, and I keep native tanks - meaning game fish). I wouldn't use anything else on a setup like mine that is not in need of live plants. The Biowheel retains all the good beneficial bacteria that is needed to maintain a healthy ecosystem inside the water, and the filters make great bacteria beds (do not change them out every 2 or 4 weeks as recommended. I keep mine in for up to 4 months at a time).
