>>By Robert Toonen and Christoper Wee

>
> This is part two of the experimental study that was discussed in this
> newsgroup a month ago. Part 1 tested tanks with no bioload. This part 2
> is more realistic, including live rock, scavengers, and some fish.
>
> Conclusions include:
> our experiment shows that the presence of a plenum has no measurable
> benefits over simply depositing the same sediments directly on the
> bottom of the aquarium
> and
> Overall, both the results of the dosing and live animal experiments
> suggest that there is no measurable difference between most of these
> common sediment filtration designs for maintaining suitable water
> parameters. There were no significant differences among depth,
> particle size or plenum treatments for the processing of ammonia or
> nitrite in recirculating aquarium systems.
