2Hr Aquarist APT Pure

Complete, super-concentrated formula removes chlorine and chloramines and detoxifies heavy metals, ammonia, nitrites and nitrates.
Contains soothing aloe vera extract.
Dose up to 5 times the recommended dose in an emergency to detoxify ammonia
Pump not included

How to use:
For most aquariums, simply add to the aquarium before adding tap water.
If you have more sensitive fish or animals, it is best to mix it with the tap water before adding the water to the aquarium.

More information:
Due to the way APT Pure binds ammonia, most test kits (both Nessler and salicylate based kits) will not work properly.
You will probably get an opaque brown result that does not match the colour chart provided.

APT Pure does not remove nitrates (or nitrites) from the aquarium.
It binds them in a form that is harmless to animals, but is also available to plants and bacteria.
Under normal conditions of use, it does not affect fertilisers or, more precisely, the amount of available nutrients that can be absorbed by the plants.
