High Ammonia

How to Know for Sure
If your test results indicate elevated ammonia levels, your fish may be showing signs of distress. Watch for changes in color—either unusually pale or dark—and erratic behavior such as shimmying, scratching, jumping, or flicking against surfaces in the tank. Rapid gill movement and gasping for air at the water’s surface are also strong indicators that your fish are uncomfortable and the water quality needs attention.

Step 1 – How to Treat Ammonia in Your Aquarium

To safely reduce ammonia levels in your fish tank, follow these essential steps:

  1. Perform a 25% Water Change – Start by removing 25% of the aquarium water to help dilute harmful ammonia levels. After a few hours, retest the water using an accurate aquarium test kit.
  2. Use an Ammonia Remover – Add a high-quality ammonia remover to neutralize any remaining toxins. Be sure to follow the dosage instructions based on your aquarium size (check the dosage guide here). There’s no need to remove carbon from your filter during this treatment.
  3. Add Beneficial Bacteria – Once ammonia levels are at a safe 0.0 mg/L, treat your tank with Fast Filter Start or another bacterial supplement. This helps boost the population of beneficial bacteria that naturally break down ammonia in your aquarium filter.
  4. Continue Regular Water Testing – Monitor your water parameters frequently to ensure a healthy environment for your fish and prevent future ammonia spikes.

Step 2 – Support Your Fish During Ammonia Stress

While you’re improving your aquarium’s water quality, it’s important to support your fish and reduce stress:

  1. Add Aquilibrium First Aid Salt – Use Aquilibrium First Aid Salt to help your fish recover and stay healthy during water treatment. This specially formulated aquarium salt supports gill function, reduces stress, and promotes overall fish wellness.
  2. Increase Oxygen Levels – If your fish are gasping at the surface, it may be a sign of low oxygen. Improve aeration by adding an air pump or air stone to boost oxygen levels in your fish tank quickly.

Supporting your fish during this time is crucial for their recovery and long-term health. Always monitor their behavior and water conditions closely.
