Aqua Perfect PH Down 200g

Aqua Perfect PH Down 200g

Aqua Perfect PH Down 200g is a pond conditioner for koi keepers who need to bring down a pH that has crept too high. One 200 g (7 oz) pack treats 20,000 litres (5,283 gal) of pond water, which makes it a practical pH control product for koi ponds in South Africa.

Why pH Matters in a Koi Pond

The pH of your pond water affects the health, colour and overall well-being of your koi. Koi do best in a stable pH range of 7.0–8.0, where their metabolism, digestion and immune system function at their best.

Key Benefits

• Helps you bring an excessively high pH back towards the 7.0–8.0 range that koi prefer
• Helps preserve vibrant koi colours
• Supports a better feeding response and digestion
• Helps reduce stress and mortality linked to poor water conditions
• Supports long-term koi health and pond stability
• Treats a pond of up to 20,000 litres with one 200 g pack

What High pH Can Do to Koi

An excessively high pH is a serious source of stress for koi and can lead to several problems:

• Loss of white colour quality: high pH can damage the skin and slime coat. The white areas (Shiroji) may then look dull, yellowish or stained.
• Reduced appetite: koi exposed to high pH often feed less, which leads to poor growth and a weakened condition.
• Lethargy and stress: elevated pH disrupts normal physiological processes, so koi can appear inactive, sluggish and stressed.
• Increased disease susceptibility: stress from unstable or high pH weakens the immune system. This makes koi more vulnerable to parasites, bacterial infections and disease outbreaks.

What Low pH Can Do to Koi

Low pH is also a concern, so the aim is a stable, balanced pond rather than an extreme in either direction. Low pH in a pond can cause the following:

• Stress and discomfort for koi
• Reduced appetite and feeding behaviour
• Hindered growth and development
• Respiratory problems and decreased oxygen intake in acidic conditions
• A weakened immune system, leaving koi more susceptible to diseases and infections

How to Use

Test your pond water regularly, because proper testing combined with pH control products keeps the environment safe and balanced for koi. Use Aqua Perfect PH Down when your readings show the pH sitting too high, and follow the directions printed on the pack.

Frequently Asked Questions

What pH should my koi pond be?
Koi thrive in a stable pH range of 7.0–8.0. In this range their metabolism, digestion and immune system function at their best.

How much water does one 200 g pack treat?
One 200 g pack treats 20,000 litres of pond water.

How can I tell if my pond pH is too high?
Test the water regularly. Koi can also show warning signs, such as dull, yellowish or stained white areas, a drop in appetite, lethargy, or more frequent disease problems.

Why do my koi's white patches look yellow or stained?
High pH can damage the skin and slime coat. This can make the white areas (Shiroji) look dull, yellowish or stained.

Is low pH a problem too?
Yes. Low pH can stress koi, reduce their appetite, hinder growth, cause respiratory problems and decreased oxygen intake, and weaken their immune system. Keep your pond stable within the 7.0–8.0 range rather than pushing it too far either way.

Why does a stable pH matter as much as the right pH?
Stress from unstable or high pH weakens the immune system. That leaves koi more vulnerable to parasites, bacterial infections and disease outbreaks.
