Ferropol is an absolute miracle weapon among the fertilizers. Since I fertilized my pelvis with this product, my plants are a lush green and sprout only at the current pace. A difference a few days after fertilization is visible. My plants are growing so fast that I have to lop a week and in addition I have thus also no formation of algae. Also in Nano Basin Ferropol is optimally applied. I recommend the fertilizer for new installation and use at every water change. Would also in combination nor the JBL recommend 7 balls again provide the additional nutrients through the roots.
