Talking about using bio-balls is talking about bio-filters, it is about the nitrogen cycle but also about the carbon cycle.
A good biofilter provides very effective remineralization with nitrate or and nitrogen gas as an end product. Produced ammonia is removed. Also, phosphate and CO2 are produced and a lot of building materials for the next generations, to be used with the produced nitrogen and phosphorus. As most organic carbon is transformed into CO2, produced nitrogen, phosphorus, and building materials are used by autotrophs, able to fix the missing carbon. Would using an algae filter to remove most of these leftovers be a good idea?
Very effective remineralization does provide a low TOC and DOC level.
What may harm corals? an increasing nitrate level, an increasing phosphate level, or an increasing DOC level?
