The right amount of Aquatek in your StainStopper is critical

The amount of iron in the groundwater varies greatly across Perth and the South West. This means the amount of Aquatek you should add to your tank will also vary. Cutting back is fine if you are testing for the minimum levels but this photo shows what happens when you go too far.

This is the same water sample, the one on the left has just 1 more drop of Aquatek in it. Makes all the difference!
