Seachem Acid Regulator™ – Create Ideal Low pH Conditions for Sensitive Freshwater Fish

Create the perfect acidic environment for delicate freshwater species with ease.
Seachem Acid Regulator™ quickly lowers pH while softening water — helping your fish thrive in conditions that closely match their natural habitat.

Key Features

• Lowers and stabilizes pH in the acidic range (4.5 – 5.5)
• Softens water by removing excess calcium and magnesium
• Ideal for sensitive, acid-loving fish species
• Helps reduce stress and improve fish health
• Supports a more natural, stable aquarium environment

Many popular freshwater species, like tetras, naturally thrive in soft, acidic water.
Without the right conditions, fish can become stressed, lose color, and be more prone to disease. Creating the correct pH range helps them stay healthy, active, and vibrant.

It is Perfect for:

✔ Neon tetras and other tetra species
✔ Discus and other soft water fish
✔ South American biotope aquariums
✔ Hobbyists keeping acid-loving species

How it works:

Acid Regulator™ lowers pH into the optimal acidic range while softening water by precipitating calcium and magnesium. This helps recreate natural conditions found in many tropical freshwater habitats.

For a fully balanced aquarium environment be sure to use Fresh Trace™ to replenish essential trace elements and feed a high-quality diet like NutriDiet® Tropical Flakes for optimal fish health.

If you're keeping sensitive or acid-loving fish, Acid Regulator™ gives you the control you need to create a stable, natural environment they’ll thrive in.
