This is my first ever forey into fertilizers that are not non-all-in-one, pre-made, liquid solutions. The docs and calculators provided by you guys and others really simplified the process and I was able to get started right away. I am seeing good growth after following the low light calculator from Rotala Butterfly and not too much algae (still new to the hobby and dosing for a month with no CO2). I could not be happier with this product. Excellent value, too. P.S. I found you guys because of your excellent blogs.
