pH kh 7.0 sets aquarium pH to approximately neutral 7 and kh to approx 7 degrees of carbonate hardness. Both pH and kh are very important to aquarium stability.
Kh the measure of carbonates is continually consumed by the aquarium biology. PH (the potential of hydrogen in water) has a direct bearing on the toxicity of ammonia produced by fish, a pH of 7 neutralises toxic ammonia if present.
Add to the aquarium at a rate of 1 teaspoon per 10 litres to automatically set pH and kh to approx 7 for both standards of measure.
Contains beneficial phosphate.
