UltraLith is a specially formulated Zeolite for reduction of nutrient concentrations in marine aquaria. This Zeolite provides nitrate- and ammonium-reducing bacteria an ideal environment. By using a composition of different Zeolites, carefully selected for their specific physical and chemical properties, this filter medium will reduce nutrient concentrations fast and effectively.
Dosing: In older tanks with high nutrient concentrations please reduce the phosphate concentrations with Ultraphos first.
Carefully wash the material before use. In the beginning, please use only 500 g of Ultralith for 400 L / 100 gal. of water. After 30 days the amount can be increased to up to 1000 g for 400 L / 100 gal.. Exchange 25 % of UltraLith for fresh material after 6 weeks.
Place the material into our special UltraLith-Reactor, use a powerful potfilter or in a place in the sump that has high water flow.Clean UltraLith weekly from sediments and detritus by rinsing it in aquarium water.To activate UltraLith, add UltraBio or similar products to the filter during the first 14 days.
