TIPS FOR USAGE
The dosage is very economical : 10 ml per 100 litres aquarium water every week.
It's also possible to add 1/7 of the total dosage on a daily basis.

 

The colour of the product can vary from dark green to dark brown. Use the first couple of weeks about 1/3 of the dosage. That can later be adjusted to attain the best possible growth rate (weekly per 100 litres 10 ml +/- 40%). The best dosage can be determined by observing the youngest leaves of the plant. If they are light green, then the dosage can be increased. When algae should appear and/or no further growth enhancement of the plants can be observed, then the dosage may be reduced. The introduction of some fast-growing plants can indeed be very helpful to prevent algae.
