Review on Tetra AquaSafe tap water treatment agent, 5 l by Dorota Mackiewicz ᠌

In the following part of the description of the product there is a typographical error: The recommended dosage is 5 milliliters for every ten liters of aquarium water. On the packaging, it says to add 5 milliliters for every 10 liters of fresh water from the faucet to the aquarium. These two measurements are not comparable in any way, as you are altering the composition of the water in the aquarium by a significant percentage (about 25 percent), and you must base your calculations on the amount of water that is being altered rather than the total volume of the aquarium.
