API pH Up for Aquarium

  • Raises pH: increases alkalinity in freshwater aquarium water
  • Colorless formula: works quickly without clouding the tank
  • Algae-conscious: contains no phosphates or nitrates
  • Plant compatible: safe for use in tanks with live plants
  • Test-kit guided: dosing is based on a pH reading before and after use

This liquid water treatment is formulated to raise pH levels in freshwater aquariums when values drop too low for the fish being kept. The colorless solution acts quickly and does not cloud tank water as it works. It is free of phosphates and nitrates, so it is not expected to encourage algae growth in the aquarium. The treatment is intended for use when setting up a new tank, correcting a pH reading, or after performing a water change, and it is compatible with live aquarium plants. Dosing is based on tank volume and should be guided by a pH test kit, with a follow-up reading taken before any additional dose is added. The product comes in a bottle and is intended for ornamental freshwater aquariums.
