Copper Citrate Algicide (Liquid) |
| 配方組成： |
Citric Acid (anhyd.)/15.2
Water/65.0
Copper Sulfate/19.8 |
| 配制方法： |
This formula contains 5% copper. It can be neutralized to pH 7 if desired using ammonium hydroxide.
Dosage: Heavy growth---1 qt for each 7500 gal or 1000 ft^3 (1.7 ppm Cu).
Lighter growth---0.4 lb for each 7500 gal or 1000 ft^3 (0.8 ppm Cu).
Note: The use of copper citrate for control of algae growth in ponds and lakes has several distinct advantages over copper sulfate treatment.
1. Copper citrate is more soluble in alkaline waters.
2. Copper citrate is less toxic to nontarget organisms.
3. Copper citrate is effective over a longer period of time due to a slow release of copper from the citrate complex.
4. Accidental overdose will not readily lead to toxic levels for other aquatic life.
The higher cost of the copper citrate system is offset by the lower concentrations required, less frequent application, and safety. There will be a slight increase in BOD.
Warning: Treatment of natural waters should be done within the guidelines of local regulations. |
