- Improves water quality in fish tanks and helps the water approach natural seawater conditions. - When the NP bean system is fully operational, it keeps nutrient levels in the tank low, not completely devoid of nutrients. - Also supports increasing the feeding amount of coral food, so corals receive enough nourishment. - Includes a spoon to add a measured amount of biological beans at any time. - Effectively improves tank water quality by promoting decomposition of nitrates and phosphates. Use scenarios - New reef tank setup: install the NP bean system to drive water quality toward natural seawater conditions and maintain low nutrient levels as the system becomes operational. - Coral care: when you want to increase coral feeding, the system helps balance nutrients while sustaining water quality. - Routine maintenance: use the included spoon to add biological beans as part of ongoing nitrate and phosphate decomposition and water quality management.
