Why API Freshwater Aquarium Salt is Essential for Your Fish

Support a thriving freshwater aquarium with API Freshwater Aquarium Salt, a 67-ounce box of all-natural electrolytes designed to boost fish health, respiration, and vitality. Derived from evaporated seawater, this safe, mineral-rich salt helps create a stable environment that promotes easier breathing and vibrant activity for tropical community fish, goldfish, and more.

Whether you’re performing routine water changes, setting up a new tank, or guiding sick fish toward recovery, API Aquarium Salt is a trusted addition to any freshwater setup. It helps reduce stress by stabilizing electrolytes and supports gill function for more efficient respiration, helping your aquatic pets stay healthy and active.

Key Benefits

  • All-natural electrolytes replenished from evaporated seawater to support respiration and overall vitality.
  • Supports disease recovery by maintaining osmotic balance during stress or illness.
  • Eases transitions during water changes and new tank setups, reducing fish stress.
  • Easy to use — dosage is simple: add one rounded tablespoon for every 5 U.S. gallons of water; salt does not evaporate, so replenish with each water change.
  • Safe for freshwater environments — formulated to support health, with a note that some live plants may be sensitive to salt.
  • Trusted expertise — backed by nearly 60 years of API experience in keeping tropical community fish, goldfish, and more.

Directions for Use

During water changes, new tank setups, or illness treatment, add one rounded tablespoon of API Freshwater Aquarium Salt per 5 gallons of water. Since the salt does not evaporate, simply replenish with each water change to maintain proper electrolyte balance and continued support for your fish.

Keep your aquatic pets healthy, active, and thriving with API Freshwater Aquarium Salt—the dependable choice for a balanced, comfortable freshwater habitat.

Supports Healthy Fish Electrolyte Levels

API Freshwater Aquarium Salt is highly beneficial because it supports healthy electrolyte levels in your fish. Electrolytes are crucial for fish as they help in osmoregulation, which means maintaining the balance of fluids in their bodies. So, when your fish have the right electrolyte balance, they feel better and are less stressed. This salt is a simple yet effective way to promote a healthier aquatic environment.

Natural Ingredients for Your Peace of Mind

This aquarium salt is made from all-natural ingredients, which means you won't have to worry about harmful chemicals affecting your fish. However, using API Freshwater Aquarium Salt can help you ensure that your fish thrive in a safe and nurturing habitat. Because of its natural composition, it's gentle yet effective for various freshwater fish species.

Easy to Use for Every Aquarium Owner

Using API Freshwater Aquarium Salt is straightforward, making it accessible for both novice and experienced aquarium owners. You simply dissolve the salt in your aquarium water, and it's ready to work. This ease of use encourages more frequent use, resulting in healthier fish over time. So, whether you're maintaining a small tank or a large one, you'll find this product easy to integrate into your regular aquarium care routine.
