API pH Down Freshwater Aquarium Water Treatment 16-oz

The API pH Down Freshwater Aquarium Water Treatment is easily one of the top solutions in our aquarium fish supplies category to optimize water conditions in freshwater aquariums. As a well-trusted product from API for aquariums, the water treatment will safely lower and stabilise pH in aquariums with excess alkalinity. Thus creating the ideal environment for fish and plants. The primary benefit of this product is the safe range of pH for fish health.

Moreover, API® pH DOWN is a pH adjuster that lowers high pH levels in freshwater aquariums, making the water more acidic when it rises above neutral (7.0), which is important since pH affects fish and plant health and should be tested regularly.
