Oh my, I guess this means that eventually I will have to remove the DSB and the sand bed in the aquarium is enough for the job. Or will it be enough to remove the top few inches of the DSB every year and replace with new sand? The main question being does the DSB still perform denitrification even with the PO4 bonding? Thus changing the top few inches would take care of the algae growth on the sand.
