FREQUENTLY ASKED QUESTIONS
Click on each question to see the answer.
Is copper sulfate safe for pools and fish ponds?
For swimming pools, copper sulfate is safe when used at recommended rates (1/2 tsp per 10,000 gallons). It effectively controls algae without harming swimmers.
For fish ponds, extreme caution is needed. Fish are sensitive to copper, especially in soft water. Use only 1/4 of the standard dose and never exceed 0.25 ppm copper. Koi and trout are particularly sensitive. Always test on a small area first and monitor fish behavior.
How does copper sulfate compare to chemical drain cleaners?
Copper sulfate offers significant advantages over harsh chemical drain cleaners:
- Environmental safety: Doesn't contaminate groundwater like caustic chemicals
- Pipe friendly: Won't damage pipes or septic systems when used properly
- Long-lasting: Kills roots at the source, preventing regrowth
- Cost-effective: One treatment can last 6-12 months
- Safer handling: Less dangerous than acids or lye-based products
Apply 1-2 lbs through toilet at night and let sit. The crystals dissolve slowly, treating the entire pipe length.
How do I make and use Bordeaux mixture?
Standard 4-4-50 Bordeaux Mixture Recipe:
- Dissolve 4 oz copper sulfate in 5 gallons of water (use plastic container)
- In separate container, mix 4 oz hydrated lime in 5 gallons of water
- Slowly add lime solution to copper solution while stirring
- Use immediately - mixture doesn't store well
Application tips:
- Spray on dormant trees for best results
- Covers fungal diseases like apple scab, grape mildew, tomato blight
- Reapply after rain
- Don't mix with other pesticides
- Test pH - should be slightly alkaline (7.5-8.0)
