ATI phosphate stop is a high-phosphate absorbers on iron hydroxide base.

ATI phosphate stop can be used particularly effectively removed from the sea water, fresh water or pond water.

ATI phosphate stop, once bound phosphate cannot be removed. Even with a longer service life of the filter material no phosphate is transferred to the aquarium water.

I remember that the concentration of phosphates in natural seawater has a very narrow range 0.03 to 0.58 mg/l. In our aquariums, we should maintain the maximum value of 0.1 mg/l (or between 0.02 and 0.08 mg/l). The lower the concentration of phosphates present, the greater the growth of corals will be, preventing-at the same time-the development of algae.

ATI phosphate stop is optimally suited for use in reef aquariums because it emits no pollutants to the water.
