API PH Down 118ml

Overview

A liquid treatment for freshwater aquariums that brings the pH down when readings climb above the range your fish and plants prefer. Water chemistry matters, and a pH that sits too high can leave some species stressed or in poor health.

Used as directed, it gives you a straightforward way of easing the pH back to where it should be.

Key Features & Benefits

• Lowers pH in freshwater tanks: makes the water more acidic when readings are higher than you want, giving many freshwater species a more comfortable home.
• Fast acting and colourless: the clear liquid gets to work quickly, with no clouding or tinting of the tank water, so visibility stays crystal clear.
• Safe for fish and plants when used as directed: free from phosphate and nitrate, so it will not feed algae growth, and it stays gentle on aquatic life.
• Simple dosing: measure according to your water volume, then re-test the pH before adding more so changes happen gradually and fish are not stressed.

When to Use It

Test the aquarium water with a pH test kit first, then use API pH Down any time the pH sits above the ideal range for the species you keep. Rises like this often follow water changes, topping up with tap water, or natural swings in tank chemistry.

Pro Tip

Adjust in small steps rather than making a large shift over a short period, as this keeps stress on your fish to a minimum.
