Liquid potassium fertilizer for planted aquariums
Enhances healthy growth and brilliant colours
Does not increase pH value and carbonate hardness
For daily use
 
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.  330ml for 6,600 Liter
