PhosGuard™ FAQ
Q:
How do I use Pond PhosGuard™? How long does it work and
when is it exhausted?
A: Pond PhosGuard™is best used in smaller quantities
and changed frequently. In an environment with an excessively
high phosphate reading, PhosGuard™ will exhaust rapidly
(4 – 5 days). Place the product in a high flow rate
area and test your phosphate levels, changing as needed. When
you see that your level is below 0.1 ppm leave that portion
of PhosGuard™in the filter. PhosGuard™may yellow
somewhat as it picks up organics, but that is not an indicator
of exhaustion for phosphate removal. Continue to test weekly
for phosphate until you see it begin to rise again. You will
then know that it is time to change the PhosGuard™. If
you have low levels of phosphate the PhosGuard™will absorb
the silicate in your system. It’s inert and safe to leave
in your filter.
Q: What makes Pond PhosGuard™different
from other phosphate absorbers and why is it not regenerable?
A: There are two forms of phosphate absorbers: iron oxide
(rust color) and aluminum oxide (white). Aluminum oxide simply
works better, and that is what we use in PhosGuard™.
The use of the bead shape results in better water flow, no
packing, more surface exposure, faster reaction. On a per
weight basis, you would have to use more of a non-bead shaped
phosphate remover than you would PhosGuard™to get the
equivalent phosphate removing capacity. None of the other
phosphate absorbers on the market are regenerable. Although
some manufacturer’s claim that their aluminum oxide based
phosphate removing products can be regenerated by intense
heat, this is, unfortunately, not the case. That claim is
based on a naive interpretation of the information provided
by manufacturers of bulk aluminum oxide. Aluminum oxide is
more commonly used in gas purification to remove volatile
organics and moisture; heating the material after such use
will release the non-covalently adsorbed compounds. However,
heat cannot result in phosphate release from aluminum oxide
due to a difference in the nature by which phosphates are
bound to aluminum oxide versus adsorbed gases.
Q: I have an algae problem hat I believe
is being caused by my phosphate levels being high.
Will Pond PhosGuard™ get rid of
my algae?
A: If your phosphates are high, there's a good chance that
is what is causing your algae problem. Pond PhosGuard™
will remove phosphates from you rwater.
