PhosBan-L is a highly-concentrated lanthanum chloride solution that has very high capacity to bind with dissolved phosphate in aquarium water. PhosBan-L easily and economically brings the phosphate concentration down to a level where you can then use PhosBan GFO to maintain it below 0.02 ppm. Add it dropwise to a protein skimmer or a 10 micron filter sock to catch the precipitated phosphate. Whether adding it by hand or with an automatic dosing system, Two Little Fishies PhosBan-L is a powerful little solution for any big phosphate problem.
