Aqua One Ammonia and Chlorine Neutraliser 500mL

Great for neutralising ammonia and chlorine.

Many of our customers use this for every water change, but you can also only use it for when ammonia levels are elevated

100mL treats 100 litres, so this bottle will treat 5000 litres of water.

For ammonia problems, we recommend that you stop feeding the fish for a week and do a 75% water change using this product to treat the new water going into the pond.

retest the water after 1 week.
