API pH UP Freshwater Aquarium pH Adjuster 473 mL (16 fl oz)

API pH UP 473 mL (16 fl oz) raises pH in freshwater aquarium water. This larger bottle provides the same pH-raising function as the smaller pack; the correct dose still depends on water volume and test results.

Key features

• Raises pH in freshwater aquarium water.
• Colourless liquid that does not cloud the water.
• Phosphate-free and nitrate-free formulation.

How to use

Test aquarium pH before dosing. Follow the dose on the bottle for your water volume, mix as directed and retest before adding more. Choose a target range suited to your fish rather than adjusting to an arbitrary number.

Important precautions

For freshwater use. Change pH gradually: some fish are sensitive to changes greater than 0.2 in 24 hours. Do not keep adding treatment without retesting.
