By supplying potassium to planted aquarium, Green Brighty Neutral K promotes plants' photosynthesis and healthy growth without increasing pH and carbonate hardness (KH). It is suitable for long-period maintenance of most planted aquariums preferring mild acidity.
To add potassium give daily one pump stroke (1 ml) Green Brighty Neutral K for 20 l water in your tank. Best time to fertilize is when the lights are on. In heavily planted tanks, increase daily dosage to two or three times the standard dosage.
