The substrate for the aquarium floor acts as the granulate for indoor plants. The growth of waterweed Ranckenpflanzen etc. is very good, large leaf plants die, however, if no fertilizer added from above wird.Ich think combined with fertilizer Co1 is the advantage if you really want to have growth in all plants, my impression is when use, it may of course be that ground Tthe combination went fail. I have above the ground concentrate, color gravel. Nevertheless I forgive 5 stars because I could not make out the source of error, obs is because of my faulty device or on gravel. The ground is enough for me to 6l for a 180L aquarium and is approximately 5-6 cm high with a uniform distribution.
