AmmoProtect™

Legend AmmoProtect™ safely, rapidly, and efficiently detoxifies toxic free ammonia in freshwater and marine aquariums. It is ideal for use during aquarium cycling, livestock transport, water changes, and emergency situations caused by ammonia spikes or temporary biofilter disruption. AmProtect™ works within minutes to convert free ammonia into a non-toxic bound form that remains available for natural biological removal by the aquarium’s filtration system.

Unlike standard dechlorinators that only break the chlorine–ammonia bond found in chloramines while leaving the released ammonia in the water, Legend AmmoProtect™ addresses both components in one step.

It detoxifies chlorine and chloramines while simultaneously binding the ammonia released from them, helping protect fish, shrimp, and other aquatic life from sudden exposure to toxic nitrogen compounds.

Ammonia in aquarium water exists in two forms: toxic free ammonia and ionized ammonium. Only the free ammonia fraction is highly toxic. Legend AmmoProtect™ is specifically designed to target this dangerous fraction without interfering with biological filtration when used as directed. The formula does not significantly alter pH, GH, or KH under normal aquarium use.

Because Legend AmmoProtect™ functions through a reducing system, some ammonia test kits may not give accurate results after dosing. Nessler-based ammonia test kits may produce false positive readings, while salicylate-based ammonia tests are generally recommended for more reliable monitoring.

Legend AmmoProtect™ also provides dechlor support for chlorine and chloramine treatment and is intended as a practical one-step conditioner for ammonia-sensitive situations.

Available sizes: 100 mL, 250 mL, 500 mL, 1 L.

Use 5 mL for every 40 L (10 US gallons) of aquarium water. Legend AmmoProtect™ may be used daily or as needed whenever free ammonia is present or expected, including during cycling, transport, heavy feeding, filter disruption, or emergency livestock holding.

At the standard dosage, 5 mL per 40 L will detoxify approximately 1 mg/L (1 ppm) of free ammonia. For higher ammonia concentrations, the dosage may be increased proportionally according to the ammonia level and the total volume of water being treated.

For advanced use, the required dose may be calculated as follows:

For volume in liters:
m = 0.125 × A × V

For volume in US gallons:
m = 0.5 × A × V

Where:

• A = ammonia concentration (mg/L or ppm)
• V = volume of water being treated
• m = volume of Legend AmProtect™ to use (mL)

Example:
To detoxify 1 mg/L of ammonia in 100 US gallons of water:
m = 0.5 × 1 × 100 = 50 mL

Reaction speed may vary slightly depending on pH and temperature. Lower pH conditions may slow the ammonia-binding reaction. Do not use in water above 30 °C (86 °F). Ensure adequate aeration during use, especially in heavily stocked systems.

For aquarium use only. Keep out of reach of children. Avoid contact with eyes. Do not ingest. Store tightly closed in a cool, dry place away from direct sunlight and excessive heat. Do not freeze.

Do not use simultaneously with active dye-based medications such as methylene blue, malachite green, acriflavine, or potassium permanganate. Use caution when applying to systems that are already under severe oxygen stress, and maintain adequate aeration during treatment.
