Aqua One Ammonia and Chlorine Neutraliser 2 litres

Great for neutralising ammonia and chlorine.

100mL treats 100 litres, so this bottle will treat 20,000 litres of water.

When your levels of Ammonia are high, we recommend first stopping the feeding for a week and doing up to a 75% water change, using this product to treat the new water going into the pond.

Retest with an Ammonia test kit after a week.
