    Hi,

    Was just wondering - I am going to install my second sump that has a DSB section this weekend and was wondering if you added a chemical would it speed up the process - SERA has some or other bacterial liquid that boosts the cycling of your tank - will this help to "seed" the DSB too?

    Or should I just try and get a cup from someone else to seed it or use some small pieces of LR?

    Maybe products like prodibio or Seachem stability will work. I'm not sure on the Sera product but both of the products I mentioned have worked for me

    Hi Pugsly,

    IMO I used the Sera Bacteria liquid to add bacteria to start the cycle. It does not "speed" up the process though! It just adds the type of beneficial bacteria into the system that would form with the breakdown of organic matter from food and flesh!! To spend the R70 odd is really not nessasary though..the same would be achieved with a piece of shrimp added to the system and left to "rot"!

    Once the bacteria is in the sysytem it needs to form colonies in sufficient numbers (millions and millions and trillions) to breakdown and deal with the breakdown and assists in the nitrogen cycle!

    Hope this helps!

    So going with a cup of the "good stuff" from someones DSB is a better option then.

    Can one purchase "Bedding" for your DSB that is already live?

    Heard it can take 6 months to get a DSB working - want to know if there is anything that will bring this down to about 2 or 3 months

    this is a stupid question I know - but can a DSB help reduce phosphate?

    I would say yes its a better option, but just remember that nature will not be hurried up and trying to bring down the time it takes to cycle can cost you lots upfront and longterm!

    A DSB is primarily used as an environment for anaerobic bacteria, whose funtion is to convert nitrate to nitrogen, to flourish. These bacteria will only thrive in the lower regions of the dsb where there isn't any oxygen. By their very nature (ie not surviving in oxygen rich environments), you wouldn't be able to introduce them manually. The purpose of seeding the dsb is also to introduce the critters that live and burrow in the sand as much as it is to introduce bacteria. The dsb will eventually develop zones of different bacteria, and this can only happen with time. Seeding of the dsb should preferably be from an established dsb that has a similar size grain to the one in your dsb. The reason for this is that different organisms flourish in different sand types (especially grain sizes).

    Diversity is the Key with a DSB.......

    mono culture is a problem.......i always look to add a cup of someones dsb to mine if i get the chance ... and my DSB is heading on 2yrs old now also a variety of live rock is essential to seed the DSB

    you can buy 2 ampules of prodibio "BioDigest"....it will populate your DSB very quickly.
    but i would use it with a combination sand from other guys tanks as well, this will help with bio diversity
