    What filter media would you suggest for a four compartment sump. Compartment one will be where the water will enter the sump, and compartment four will house the return pump.

    I wouldn't waste compartment one by leaving it empty - neilh's suggestion looks good.

    I agree – compartment one will be used for mechanical filtrations and compartments two & three for biological filtration. But as we all know, some products are of a much better quality than other. Do you have any suggestions of specific makes of sponges and bio media that would filter the water better that others.

    As a filtration media? Interesting, never thought of that. In theory that could work very well due to its porous nature.

    Sera Siporax or Eheim Efubstraat. Both are eye-watering expensive

    What about Seachem Matrix. Has anybody use it, or heard some good report on the product.

    Hydroton - seems like a product that will be able to do the job. pH neutral and very porous. But also expensive. About R700 for 10 liters.

    Correct me if I am missing the plot totally:
    1) Ammonia is converted to Nitrite, and then to Nitrate by aerobic bacteria.
    2) If you add a airstone to the biological filter in the sump, would this improve the efficiency and enhance the growth of the aerobic bacteria.

    If you are running Co2 in the tank, that is a bad idea. But yes, in theory it should work.

    Hydroton IMO is the filter media to go for when looking for a good biological filter media. It has a surface area of about 280 sq metres (8-12mm grain size if I remember correct) which costs R15 per Litre compared to Eheim Substrat Pro which has a surface area of 480 sq metres (again if I remember correct) that costs about R120 wholesale! So for me Hydroton is the way to go...

    Things to remember:
    - prewash thouroughly before putting into the filter
    - it is light and will float, subject to how you use it
    - it is completely inert and will not alter the pH
    - if possible get 50/50 mix of the 2 grain sizes available locally - again subject to the application

    and R700 for 10 Litres is an absolute rip-off...
