Water Conditioner.
I have a 100 liter aquarium with turtles. This water conditioner has become the best for me of all those that I have bought before. I do a water change once a week, with this water conditioner even after a week the tests show that the water parameters are normal. Although I have used various other water conditioners before, recently I have been using AquaSafe and NitrateMinus, but after a week the tests showed an increase in nitrates. I am very happy with this water conditioner, I definitely recommend it.

Good value
Worked as expected, the water took time to clear. Instructions were on the bottle. Straightforward to use. The cap also functions as a measure. Worth it. Good size bottle too.

As good as it gets.
I use this by the gallon. It takes a little more liquid than Prime, but it’s very safe and affective. I don’t need to remortgage my home to by a jug.
