I'm just recently heard about the Biopellets. From what I can tell, they are another way of carbon dosing. I have read you cannot overdose and that the bacteria stays contained in the reactor so you don't have to worry about stringiness in your tank. So other than cost are their any downsides to this product? Speaking of cost, it sounds to me like they last a fair amount of time. For say a 100G typical tank how long would a 500ml bag last?
