Masterline I, II and Carbo is my favorite fertilizer formula. It provides all the nutrients my aquatic plants need. It's easy to use and has several dosing options. I can use it for strong and fast growth or even for slow growing plants. The color of my aquatic plants is remarkable.

MasterLine is not just a brand, it's a concept that is always improving, progressing, diversifying, seeking to understand the needs of the aquarist and to meet these needs with an exceptional product at an affordable price. I recommend it to all aquarists no matter what level they are at.

Kevin Hoehlein

I have tried many fertilizer systems and many worked well. However, I was never completely satisfied with the densely planted aquariums and the demanding plants. MasterLine made possible what other fertilizers could not.

Emilia Mija

MasterLine is the fertilizer used in our family for over 4 years. It gives us the joy of growing beautiful and healthy plants from those with easy requirements to those with a high degree of difficulty, without problems. It's an easy fertilizer system to be used by both beginners and experienced aquarists.
