2. A primary purpose in aquariums and ponds is to protect aquarium and
pond fishes and invertebrates by quickly eliminating (actually
detoxifying) the harmful components of the biological nitrogen cycle -
ammonia, nitrites, and nitrates without slowing the nitrogen cycle
(see KPD-64 "Biological Filtration"), or interfering with the
beneficial bacteria involved, or depriving these bacteria of their
food.

To control the toxic organic nitrogenous compounds of ammonia,
nitrite, and nitrate and other toxic organics that build up in
aquariums and ponds from the excretion of body wastes by fishes,
invertebrates, bacteria and other aquatic organisms start with a
Standard Dose (see definition above). This Standard Dose will remove
(detoxify) at least 1.2 mg/L (= approx.1,2 ppm) of all ammonia
compounds, at least 2.0 mg/L (=2.0 ppm) of nitrites, and at least 13
mg/L (=13 ppm) of nitrates. We recommend only one standard dose per 24
hour period. The removal of these compounds will happen within five
minutes, or slightly longer for ammonia at a higher pH above 7.5. It
is important to understand that the amounts of organic compounds
removed may vary with differing water conditions. The amounts
indicated above are the minimums that AmQuel will detoxify, and what
is removed may be up to several times higher. Use accurate test kits
to check how much of each compound is being removed when using
multiple doses (see the section in KPD-80 on "Water Quality Test Kits"
under "Problems When Using Water Conditioners..."). Be aware that test
strips may be insufficient to provide accurate readings; check liquid
and powder reagents to be sure that they are not out-of-date.

So, according to their own support page, Amquel + does handle 13 ppm
of nitrates.

Use Amquel next time. It's the best friend to a Python system. Works quick,
and eliminates Nitrates and Ammonia.. nitrites too!!


Can you provide some support for the claim that Amquel
eliminates nitrates? Where do they go?

"AmQuel quickly and effectively removes ammonia, chlorine and chloramines"

Please think before you post erroneous information.
