Product Information




CaribSea Phosbuster Pro 1 gallon

PhosBuster Pros unique patent pending formula removes dissolved phosphates in minutes instead of days. Safe for all reef tanks, saltwater, and freshwater aquariums of all sorts.

Each 1 gallon. bottle removes at least 1.5 ppm in up to 4000 gallons of water! No more fiddling with filter bags, or special reactors; just dose it and forget about your phosphate problem. Phos-Buster Pro may be used regularly as part of a preventative maintenance program.

How does PhosBuster Pro work? PhosBuster Pro chemically binds and precipitates phosphate into an inert compound that is stable in the aquarium and is then filtered out, through protein skimming.

Will the phosphates dissolve or reintroduce back into the water column? No, it is not possible in aquarium situations the phosphates are tied up in a compound that is insoluble under normal aquarium parameters.

Direction of Use Add 1 capful (5 ml) of PhosBuster per 5 gallons of aquarium water (1 ml per gallon). Place in the sump or any high flow area of the system for rapid dispersal. Some temporary cloudiness may appear. Desired results should be achieved within 72 hours depending upon level of phosphates in the system. Keep all filters running during this time period then rinse or replace filter media. Retest water for phosphates and repeat treatment as needed. Each treatment will remove 1.5ppm of phosphate from aquarium water. PhosBuster may be used monthly as part of a preventative maintenance program.
