AQUAYER pH/KH minus 250mL

AQUAYER pH/KH minus – efficient agent for decreasing carbonate hardness (КН) and рН of water in aquarium. Many tropical fishes feel better in water with carbonate hardness less then 5° dKH (German degree of hardness) and pH lower 7.5. Moreover, aquatic plants better grow in such conditions. Regular usage of pH/KH minus helps to keep optimal рН and carbonate hardness.
Does not increase concentration of phosphate in aquarium water.


To decrease pH and carbonate hardness add no more then 25 mL of AQUAYER pH/KH minus for every 100 liters of aquarium water. Repeat procedure every 2-3 days until desired carbonate hardness is achieved. Each dosing will cause carbonate hardness decrease for approximately 2° dKH. During the procedure water aeration must be turned on. CO2 injection must be turned off. Regularly check carbonate hardness with AQUAYER test pH+KH to avoid its decrease lower then 2° dKH and dangerous pH drop.
Long-term regulation of carbonate hardness and pH. Add 5 mL of AQUAYER pH/KH minus for every 100 liters daily. Such dosings increase carbonate hardness approximately for 0.4° dKH every day. During this procedure CO2 injection can be turned on.

Volume: 250 mL.

Keep away from children. Do not take internally. Avoid contact with skin and eyes. In case of eye or skin contact rinse immediately with plenty of water.
