    Planted tank success in a bottle!

    Managed to put together a decent planted tank after failing several times over the past 2 decades. This is despite the fact that I have an unconventional setup with no gravel. Highly recommended!

    Great for tanks with more or larger fish

    I use to use APT Complete. No issues with it at all, it worked great and my tank was doing very well. After adding a few boesemani rainbows to my tank I got a staghorn bloom that was hard to get rid of. I raised my lights a little bit and switched to Zero. The staghorn went away but it was followed by green hair algae that I was able to correct by manually removing it and bumping up the bubble count. The plants took a couple of weeks to adjust to the new nutrients and light adjustment but it has finally settled in. Still not perfect but there will always be some algae. Just keep up on the maintenance and try not to let it get too far ahead of you https://youtu.be/6dnGipQ7-jw

    A perfect fertilizer position between lean and heavy dosing. Easy to use and very economical.

    Maintain's the balance in my tank!

    Great for moderate planting levels even in mostly fish dominated tanks. Used this in my semi planted altum and discus tank.
