    Smooth transition

    Well, firts of all I was a little worry about switching ferts (before APT I was using other brand with separate elements). Decided to try APT because of three main reasons: 1) Wanted decent "all in one" because of getting tired dosing separately every element. 2) APT has greater amount of phosphate than other brands I considered (my aquarium loves P). 3) Producer dosage is real, efficient dosage. Transition went great. My plants seems to be more happy with APT :) Thank you for great product!

    As always the best fertilizers. Would love a bigger bottle size too!

    Very effective and useful for plants.

    Tired of using NPK addition once change water or add expesive products for that, H2r seems to be my best choice. Plants have grown a lot, with no algae. So I should recommend it. At least check, if you're not convinced to change your system, once. Your trial is worth.

    I've tried other fertilizers without much success, however, since I've changed over to APT complete it's been an amazing change for my plants. Within a few weeks I've noticed a difference with the growth and color of my plants. This is my only fertilizer I will use, and I have been recommending it to friends and family members who have planted tanks. Thank again for this wonderful product.
