Saturation point of ammonia processing by filter type.

[Galabar]

I noticed an interesting experiment online where various filters were set up and ammonia added over a period of time to determine the efficacy of various filter types.

One interesting finding was that the tank gravel alone was not very good at converting ammonia, with cannister and undergravel filters doing a solid job, and large fluidized beds being the best.

Has anyone tried this?

I’ve not done any experiments. The capacity for biofiltration depends on oxygenated water moving over surface area where bacteria grow. So those filter types that move the most over the most surface are logically to be the best. Thanks for sharing.
