Yeah, but in that case, why use foam - you'd be way better off filling that basket with a quality filter media.

Also, are we taking Aquarium Science at his word...... I'm highly dubious of that site!
Hi all,
If you are asking me whether his opinion, or that of <"Stephan Tanner">, <"Timothy Hovanec"> etc are more likely to be right than that of the <"vendor of Biohome?"> I would say they definitely are.

It does, but one thing you have to bear in mind is that the author of Aquarium Science has <"insane stocking rates">.
A lot of <"Monster Fishkeepers use pot scrubbies">, mainly because of their non-clog nature.
That is the real issue, <"no scientific data"> and a lot of statements that are <"dubious at best">. I just use <"whatever I have to hand">, it all "works" and once you know that it is oxygen that is the important bit everything else is just <"re-arranging the deck-chairs on the the Titanic">.
I'd say foam can be a <"quality filter media">. The <"majority of serious fish-keepers">, who have fish-houses, use an air pump, air ring and foam filtration.
Yes I'd agree the planted tank pages are <"interesting">, but the pages on aquarium filtration are (in my opinion) pretty good. I've done some work on the <"bioremediation of landfill leachate"> so I have some scientific understanding of the processes involved.

How do you define quality media?

Interesting, what is the long and short of the research then - basically that we should just fill our entire filter with foam?
Hi all,
You don't need to fill the filter body with foam, but you need to make sure you don't have any bypass. My main use of foam <"is as a pre-filter">, usually <"as a DIY version">. In recent times I've mainly used the <"Koi type drilled sponges">, they are cheap and they work effectively.

I honestly don't think it matters that much what you use. If some-one else is buying I'll have <"Eheim Coco-pops">, mainly because they aren't made of plastic and will last eternally. If I'm buying my own? Generic Kaldnes type floating cell media, <"Alfagrog or Hydroleca">.

Yeah well its an interesting question. Why are HMF successful when they don't seem to function as typical biological media do ie your k1, and ceramics etc.
I bought a few of those pool filter sponges, and inserted a cheap filter. I cut them in half then block off the other end with some fine pad. I have one running in a small shrimp tank, and it works great.
Where do you get those then? I’ve been looking for some with a large enough hole to accommodate my 25mm intake pipe.
I found them on Amazon. Just search for 'pool filter sponge'.
Hi all,
The problem is that if the <"BOD exceeds the oxygen supply"> aerobic nitrification will be compromised and levels of ammonia and/or nitrite will rise.
In an HMF it is in contact with the atmosphere at its top and the oxygenated tank water bathes it.
There is a description of how an HMF works in <"on Aquarium biofiltration">, in our terms it is <"fulfilling the role of both filter and substrate">.
The latest incarnation of the <"Kaldnes media"> includes some <"carrier biochips"> that are designed to support and protect Rotifers, Protists etc.

It is different for HMF (and trickle filters etc.). In a canister type filter <"a finite amount of oxygen"> enters the filter and it can only be replenished as new water flows in.
