API® AQUARIUM SALT is made from evaporated sea salt and is a must-have for your aquarium! AQUARIUM SALT promotes fish health by improving gill function, making it easier for fish to breathe. It also provides essential electrolytes that fish need to reach peak coloration and vitality. These electrolytes may be lost each time you perform a partial water change, and will need to be replenished.

Use API AQUARIUM SALT in freshwater aquarium tanks when starting a new aquarium, and any time you perform a water change. Care should be taken when using salt in aquariums with live plants, as some plants may be sensitive.

Available Sizes: 16 oz, 33 oz, 65 oz

API® pH DOWN pH adjuster lowers pH to make freshwater aquariums more acidic for fish and plants when levels rise too high. pH is the measure of acidic or alkaline conditions in water, where a value of 7.0 corresponds to a neutral pH, pH values about 7.0 are considered alkaline, and pH values below 7.0 are considered acidic. Different fish need different pH levels to be healthy, so it is important to test your water regularly to ensure pH levels fall where they should. pH DOWN pH adjuster is fast-acting, colorless, easy to use, and will not cloud aquarium water. Because it is phosphate-free and nitrate-free, pH DOWN pH adjuster will not encourage algae growth.

Available Sizes: 1.25 oz, 4 oz
