Crystal Clear Phusion Down naturally lowers pH levels in ponds. Brings pH levels down to optimum levels of 6.5-7.0 Helps fish keep a healthy slime coat and stay healthy by adding necessary electrolytes to the water. Great for use in fish ponds, koi ponds and goldfish ponds without the danger of putting fish in shock. Safe for pets, plants, birds and domestic animals that may drink from the pond as well as aquatic fish.
Add 4 teaspoons for every 1000 gallons of water. pHusion lowers pond pH levels 0.2 points per application. pHusion may be added every 24 hours until desired pH levels are reached.
You will get true readings if you test your pond water in the morning rather than in the evening.
If the pH level in your pond is 9.0, it may take up to 10 applications until you reach the desired pH level.
Optimum pH levels for ponds are 6.5-7.0
