    Hi guys,

    Came across this vid while browsing.

    Do you think it would work in a marine setup?

    Yup you can use that type of filter. Also known as a fluidised bed filters. They can be either aerobic or anaerobic.

    Aerobic filters are used to quickly remove fish wast and convert the decaying matter to Ammonia then Nitrite. You will need to have a good Nitrate filter to remove the nitrate the Aerobic filter creates.

    We make use of fluidised aerobic filters and trickle towers on tanks that are heavily stocked and receiving ice cream tubs full of food a day.

    In summary. Not a good idea for a small marine tank with corals unless you have a very good Nitrate filter.

    Looks cool. What media should be used in it and what would be a good Nitrate filter to combine with this?

    Media could be anything from fine coral sand, silica sand, stinted glass, plastic beads, bio balls etc anything that has a large surface area. The smaller in diameter the media is the bigger the surface area by volume. Don't go two small because then the fine sand tends to float out into the tank. Something between 2 and 3mm diameter is cool for sands.

    For a nitrate filter you could DIY something like this.
