    Only Fertilizer I will use

    APT zero has been perfect for my planted tank. I have slower growing lower light plants with co2 injection and I have seen no algae growth in 8 weeks of using this product. Just let my fish provide the nitrates with their waste and ATP zero does the rest.

    5 Months In on First Planted Tank and Couldn't be Happier

    This is my first planted tank. I did a ton of research before starting and am so glad I did, as it helped me avoid a lot of first time mistakes that could have been both costly and unsightly. My tank is fully automated (water in, water out, dosing, temp, etc.). I chose 2hr aquarist because they had additives that were specifically formulated to meet my needs with a minimum of work. I have been incredibly happy. The plants are thriving, even the notoriously finicky ludwigia pantanal. The colors are absolutely beautiful. Fish are happy. Water parameters are 100% stable. I couldn't ask for more.

    Repeat customer!

    I tried these ferts a few months back when I noticed that my nitrates were climbing too high between water changes and I was developing all sorts of algae in my well established tank. Since switching to APT Zero I've had none of these problems and the plants are thriving. Highly recommend if you're serious about great plant health and vibrant colors.

    This Stuff Works!

    I’m on my third planted tank and using APT Zero for the first time. Finally my plants are thriving, and without C02! It’s nice when a product does what it advertises. Thank you!
