IT WORKS BETTER
WHAT IS IT?
Modified Granulated Ferric Hydroxide Oxide (GFH) phosphate, silicates,
arsenic and heavy metal remover.
COMPOSITION:
Fe(OH)O, granules in fully hydrated form.
PURPOSE:
To be used in fresh and salt water aquariums to remove large quantities of
phosphate, silicates, arsenic and some heavy metals.
BENEFITS:
- Maintains extremely low to non-measurable levels of phosphate and silicates thus greatly reducing propagation of algae.
- Removes arsenic and other heavy metals.
- Safe for the most delicate invertebrates does not contaminate water with iron.
- Extremely low impact on trace elements and desirable fertilizers like potassium.
- Non-leaching, permanently and irreversibly binds phosphate and silicates.
COMPARISONS:
Comparison of different phosphate removing products marketed for use in
aquarium applications is challenging for one main reason: all phosphate
removing medias are designed for use in open-loop applications such as
cleanup of drinking and waste waters, where contaminated water passes through
the media bed only once. Use of such medias in aquariums is greatly
complicated as aquariums are closed-loop systems, where water passes through
the media repeatedly. PhosLock is the first and the only phosphate removing
media that utilizes GFH specifically modified for use in closed-loop
applications. Let us review some data on testing media performance in a real
aquarium application.
Comparing to products such as PhosBan and Rowaphos, PŪRA PhosLock is 10% more effective than PhosBan and 3.0% more effective than Rowaphos in removing phosphate from fresh and saltwater. It seems that all three brands perform very similarly in removing phosphate, but this is not the entire picture.
Large quantities of free iron in aquariums are known to cause permanent damage to fish gills. PhosLock is much harder and far less prone to disintegration in high flows compared to the other brands.
Over 72 hrs of use one gram of PhosLock releases less than 0.02 mg of iron comparing to 3.7 mg per gram of Rowaphos and 98.8 mg per gram of PhosBan. That is 185 times less than Rowaphos and 4940 times less than PhosBan.
Recently appearing on the pet markets granulated and palletized medias based on Bayoxide E33 product are about 14% less effective in removing phosphate and release 270 mg of iron per gram of media that is staggering 13500 times more than PhosLock.
