Dupla Siliphos freshwater
700 g for 6.720 l
An effective phosphate and silicate remover based on iron hydroxide for fresh water aquaria. The moist granulate has an extremely high binding capacity and reliably solves phosphate and silicate related algae problems. To prevent phosphates concentrating in the decoration or the substrate, it is best to use Siliphos right in the beginning when setting up the aquarium. 150 g for 1.440 l at 0.5 mg/l PO4 in the freshwater aquarium. Includes net filter bag.
