Reef Interests Biopellets XL

Reef Interests Biopellets XL pellets are ideal if you do not have a fluidized reactor

The larger XL pellets are ideal if you do not have a fluidized reactor because they don’t need the higher water flow that the smaller size pellets do. You can just put them in any type of filter that has moderate water flow, they don’t need to tumble. You could even just lay them in a compartiment in your sump. As long as water flows past them, they will function.

BioPellets are consumed by bacteria, which is why new pellets need to be added every 6-12 months to compensate for digested substrate. This can be seen during inspection of the filter or when you measure a increase of nitrates.

These figures however depend on aquarium conditions and are strongly influenced by feeding regimes and livestock. Taking regular measurements of both nitrate and phosphate levels in the aquarium is recommended, after which dosages may be increased or decreased. Of Note, NP-reducing BioPellets consist of a higher molecular mass than most competing products resulting in a longer filter retention time and thus requires less frequent refill then other low molecular weight products which are currently being marketed.

We suggest placing the outlet of the pellet filter in front of a protein skimmer, to limit the amount of bacteria entering the system. This has the additional benefit of increased gas exchange (CO2-removal and O2-addition).

The pellets should never be used without sufficient aeration, as this may lead to low oxygen and pH levels, especially during night time. Proper aeration can be established with air pumps and protein skimmers.

The BioPellets will allow more feeding and thus more livestock, however, when heavy feeding is required, it is recommended to combine the pellets with standard phosphate adsorbents.

The reason for this is that most aquarium feeds contain higher levels of phosphate than is consumed by bacteria, fish and invertebrates, when compared to nitrogen. Some phosphate adsorbents however deplete alkalinity and may reduce pH.

Using phosphate adsorbent media based on iron hydroxide does not have this disadvantage.
