| Special preparation for reducing the pH-value. When preparing fresh water the Pharma 6 is added drop by drop into the moved water until the pH-value desired is reached. If the aquarium or pond is lived the increasing should be maximum by 0,2 pH per hour. Use it, specially in seawater, earliest 20 hours after last feeding. The consumption depends an the hardness of the water. For DH 2 (German hardness) about 12 drops are needed to change 100 litres of water to reduce by pH 0,1. For DH 10 you will need about 50 drops to achieve the same varition. Remarks 1 DH (german hardness) = 0.798 british hardness. |
