    hey, often i read that bio balls give problems eventually... this is just my opinion but u should have a deep sand bed. SAnd around 15cm deep with no rock on it and water flowing on top of it.. filter media like sponges become nitrate factories.. im not sure if u have to do it this way but most of the other guys have the skimmer in the 1st or 2nd chamber then a DSB then a return... so maybe u can just make 1 chamber a DSB and put the rock in the 3rd chamber and skimmer in the 1st... but thats just my :) opinion .. sure the guru's will give better advice :thumbup:

    Like Treyman said, Sponges are a now go! Chuck them out and move the skimmer to the firts compartment,then you can change the second compartment to a DSB, a DSB is just very fine sand 0.3mm to 0.5mm in the sump compartment but it has to be 15cm or thicker to become effective... You can read more about it at the articles. The third chamber you can place chaeto and light for nutrient export and last chamber will be the return pump.

    first question, what livestock do you want to keep? And what is your goal?

    For a fish only system, bio balls are 100% OK. Ceramic rings are more prone to have detritus built up and are more difficult to stir it once in a while to get rid of detritus built up. But it will give same function as the liverock you got there.

    The sand you got there does not help a lot. A bit yes, but a 15cm deep DSB is the best option. But it should have the biggest footprint you can get. That is why a 3 chamber instead of 4 chamber is better. Can put cheato in area above DSB. But you need a globe, like a CFL is OK

    Also, filter sequence should be, Mechanical, Biological, Chemical.
    So that is Skimmer,
    then DSB and or cheato and or live rock
    then carbon and phosphate reactors plus return pump.

    Anemones prefer good water parameters. It is easier to maintain those parameters with a DSB than with bio balls. DSB provides the complete nitogen breakdown cycle, where bio balls stop half way. Also a DSB with Cheato or DSB with Scrubber provides a lot better biological filtration than bio balls. Even better with DSB, Scrubber and Cheato. Other benefits like more life diversity is a bonus.

    I will make the DSB deeper between 10 and 15cm, depending on how fine the substrate is. And lift or suspend the live rock just above the dsb, as not to create dead spots, or spots with slow flow.
