PÛRA Complete is an All-In-One media that provides the most complete aquarium pollutant control at low cost.
Blended with 25% PhosLock for total phosphate and silicate control, virgin bituminous acid washed carbon, and cation exchangers for the control of ammonia and heavy metals, PÛRA Complete offers a truly impressive spectrum of activity.
BENEFITS:
Removes phosphate and silicates thus greatly reduces propagation of algae.
Removes large quantities of ammonia and formaldehydes.
Removes copper, arsenic, zinc and other heavy metals.
Removes a broad range of organics like urine, phenols, coloring agents, odors, proteins and residual medications.
Extremely low impact on trace elements and desirable fertilizers like potassium.
Convenient to implement, comes with a 6" x 12" 300-micron media bag.
PURA Complete is fast acting, long lasting, and very effective in reef, marine, planted, and delicate freshwater aquaria. The 8 oz will treat a 50-gallon tank up to 6 months. PÛRA Complete should be used instead of plain carbon, and no additional "specialty media" are necessary to provide total, complete, and cost effective aquarium waste management.
