    BRS Bio Pellets are PHA Bacteria Boosters

    As we predicted, discount or bulk sellers are now getting into the solid carbon dosing or BioPellet game. Most notably, Bulk Reef Supply (BRS).

    brs biopelletBased on the limited number of suppliers, we feel safe in guessing that the BRS Bio Pellets are PHA or Polyhydroxyalkanoates. Seeing as most of the PHA suppliers do not give significant discounts on the type of volume the aquarium industry turns over, it will be interesting to see how aquarium companies price and distinguish themselves. Currently 500ml of BRS BioPellets will cost you $38.99 which is spot on to pricing for the Vertex Pro BioPellets (also PHA). Likewise, for 1000ml both products come in at approximately $70 USD.

    Interestingly BRS, notes the importance of contact time with their product. Initially biopellets were marketed as safe, and unable to be overdosed. This is not the case. “Dosing” with these biopellets is a function of surface area and water turn over, or contact time.

    “Dosing” of BRS Bio Pellets:

    “The speed at which the media tumbles will have an effect on the system because it is a combination of two things, contact time with the media and the amount of times a day the entire system water volume passes through the reactor. Every tank is going to have a sweet spot in terms of contact time with the media and how many times the entire water volume should pass through the reactor each day. In general we recommend trying to maximize the contact time with the media which means tuning the reactor so 100% of the media is just barley tumbling. Going slower runs the risk of the bio pellets sticking together with biofilm. ¬†Faster flow reduces contact time, but increases system turn over. Please feel free to experiment with this after the 8 weeks.”

      This bio-pellet craze sure is fascinating. I get the feeling that these polymer pellets can be found elsewhere, being used for some other cause. I am glad that the costs are coming down but I don’t know if that is best for sellers considering the fact that hobbyists don’t have to change the pellet media for at least a year.
