general key for filtration

[softturtle]

Why is it necessary to run so much more volume through the filter if the end result will be the same? It's not necessary. Simple.

In some cases to much water movement can decrease your filtration capabilities. Your bio media likes to have a little time to convert toxic ammonia into nitrite, and toxic nitrite into nitrate (I think this is the right order, I all ways get it mixed up). Anyways, in some filters to much water flow can actually strip your bacteria from your media. So this could leave a lot of your bacteria in the wrong spots (gravel for instance, which is basically useless if you don't use an UGF to flow water through there).

So, I have never had a tank that turns over ten times and I don't think I ever will. I do my regular water changes. My readings are near zero all the time and my tanks are spottless.

This is making a lot of sense. Its not the size of the pump but the size of your Bio Filtration that your using. Thanks everyone for explaining it in easy to understand terms.

That's if your mechanical and bio are together. If mechanical only, you can have a high rate designed to trap pollutants efficiently.

This is a hard question to answer. It all depends on your stocking levels and water changes. I personally think HOBS do a better mechanical job than canisters.
