The colour of leaves and growth of plants tend to get thinned or suppressed if a lack of nitrogen occurs. Supplying nitrogen to the planted aquarium improves the colour of leaves and growth of plants. This fertilizer does not contain phosphate.
To add iron give daily one pump stroke (1 ml) Green Brighty Nitrogen 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.
When setting up your substrate, spray Green Brighty Nitrogen with the help of a spray bottle on the flattened surface of the dry soil. Use 50 ml Green Brighty Nitrogen for an 30 x 30 cm area. Wait 15-30 min to let the soil soak up the fertilizer completely before filling up the tank with water.
