Tropic Marin® NP-Bacto-Pellets must be used in a fluidised bed reactor. A strong skimming of the aquarium water is advisable for removal of nutrients and gas exchange.
Pour boiling hot water over the Tropic Marin® NP-Bacto-Pellets and let soak for 2 hours before use to expel excess air. Start with 50 ml/1.5 fl. oz. of Tropic Marin® NP-Bacto-Pellets per 100 l/ 26 US-Gal. of aquarium system volume. If necessary, double the amount after 4 weeks. A maximum quantity of 200 ml/6.5 fl. oz. per 100 l/26 US-Gal. of aquarium system volume should not be exceeded. We recommend replenishing consumed pellets every month.
For particularly rapid and effective nutrient reduction, the outlet of the pellet reactor can be directed into the vicinity of the protein skimmer feed.
After two to four weeks, you will notice and can measure the reduced nutrient levels in the aquarium.
