Blue Planet pH Down 200g
Measuring water chemistry (pH Levels) in your aquarium and pond is essential for establishing whether the water is healthy for your fish.
Directions for use: We recommend that you allow some time to alter pH as it is better for your fish to become accustomed to the changes slowly.
As a general rule, use 1 tablespoon of powder per 100 litres of tank water, first dissolved in a small cup of aquarium water, then add to a flowing area of the aquarium.
Use a test kit 1 hour later to check the change in pH value. Repeat the process up to 3 times a day, testing in between.
As aquarium water chemistry varies dependant on pollution levels, dissolved organic waste and carbonate hardness, it may take several times to get the right pH level. Please allow a few days to alter pH values over a large scale. An aquarium with no fish or live plants present can be altered quickly.
