We’ve covered plenty of biopellets here at Reef Builders but the NP-active pearls by Dr. Tims creation are a bit different. Although the NP-active pearls look pretty much the same as most on the pellets on the market, these pellets are made from 100% PHA (polyhydrocyalkanoates) which is made from bacteria which in turn means that these pellets are completely biodegradable. These pellets are also made locally in Iowa, and the origin of the product is openly provided (Mirel). More info can be found on the NP-active pearls website. Retail price is currently still unknown but we expect them to retail around the same as the other pellets on the market.
