High Ammonia in Aquaculture Ponds: Fast Control & Long-Term Solutions
Control toxic ammonia (NH3) in fish and shrimp ponds. Yucca saponin application, C:N biofloc balancing, and nitrifying bacterial cultures.
Visible Symptoms
Shrimp with red or blackened gills; lethargic swimming near edges; test kits indicating TAN > 2.0 ppm or toxic NH3 > 0.05 ppm; high feed refusal.
Primary Causes
- Overfeeding leading to protein waste accumulation.
- High afternoon water pH (> 8.5) driving toxic un-ionized NH3 conversion.
- Incomplete nitrification due to low dissolved oxygen or low alkalinity (< 100 ppm).
