Sunken Garden Goldfish Water Conditioner: Dechlorinator and pH Support for Goldfish Aquariums 

What is Sunken Garden Goldfish Water Conditioner?

It is a liquid water conditioner made for goldfish aquariums. It neutralizes chlorine and chloramine in tap water, supports pH stability, and supports the beneficial bacteria in your filter. It is used at every water change to make new tap water safe for goldfish.

Why do goldfish need a water conditioner?

Goldfish produce a lot of waste, so they need frequent water changes. Tap water usually contains chlorine or chloramine, which can damage gills and stress fish. A conditioner makes new water safe before it goes into the tank.

How much conditioner per litre?

Use 1 ml per 5 litres of tap water. That is 0.2 ml per litre.

How do I use it?

1. Shake the bottle well.
2. Measure the volume of new tap water you are adding.
3. Add 1 ml per 5 L of that water.
4. Mix evenly, then add it to the tank.
5. Repeat at every water change and at new tank setup.

Does it support pH stability?

It is formulated to help keep pH steady during water changes, which reduces stress from sudden swings. It does not replace testing: check pH with a test kit, since goldfish generally do well in stable, neutral to slightly alkaline water.

Does it contain beneficial bacteria?

It supports the beneficial bacteria that break down fish waste. 

When should I use it?

• Every water change
• New goldfish tank setup
• After transporting or introducing goldfish
• During recovery after medication or illness

Which goldfish is it suitable for?

All goldfish varieties, including common, comet, fantail, oranda, ryukin, ranchu, lionhead, pearlscale, and shubunkin, in freshwater aquariums.
