Tropic Marin NP-Bacto-Tricks is a biodegradable trickling filter media for reducing nitrate and phosphate levels. Tropic Marin NP-Bacto-Tricks provide an effective means of reducing the levels of nitrate and phosphate in aquariums by acting as trickling filter media. Tropic Marin NP-Bacto-Tricks consist of a mixture of natural biopolymers, which are removed by bacteria and other aerobic microorganisms. As they grow, they extract nitrate and phosphate from the water and thus produce valuable biomass, which serves as food for filter feeders or can be skimmed off.Tropic Marin NP-Bacto-Tricks+ easy-to-use trickle filter media for the effective removal of nitrate and phosphate+ due to the compact size, it is suitable for ventilated bioreactor systems+ made of natural biopolymers, which promote the colonization and growth of nitrate and phosphate removing bacteria as well as other aerobic microorganisms+ the valuable biomass is then made available as a food source for filter feeders or can b
