Plant crack

I must say I did not have much faith in it because it’s so cheap but it works really well. Within a week I saw new shoots and roots coming from my plants. Don’t let this bright green liquid scare you like me. The only thing to be careful with is dosing, since it’s basically concentrated nutrients it attracts algae fairly quick.

Love the Brand

You can't go wrong with API, do some research on how to properly use it and it's worth every penny.

Easy to use and seems safe for shrimp.

I bought this along with 3 Seachem products to really give my plants a boost. I was only using the 3 Seachem (Trace, Advance, Flourish) in my planted tanks and then my shrimp tank started having molting issues. I stopped the Seachem and switched to Leaf Zone and so far so good! All plants are doing well.

Worked for me

I had a Java plant that was rapidly declining and when I started using this it helped. I wouldn't say that it's helping very much, it's not all that my plant needs, but it stopped it from dying so I'm happy with it.

Don't waste your money!!!!

This product only has 2 ingredients and are minimal to what your plants really need. If you think this stuff is working on your plants your wrong, it’s your fish poop that’s doing all the work. Do your plants a favor and buy Seachem flourish and your plants will thank you.

This is a great plant fertilizer

This is a great product, I've used it for years for my planted tank. It fertilizes the plants but doesn't cause algae growth.

Makes Plants Grow FAST!

This stuff WORKS! I have a 5 gallon low-tech heavily planted nano aquarium. With no CO2 and a pretty basic full spectrum light, my plants flourish thanks to API Leaf Zone. I add it once a week and literally the next day my anubias and banana plant sprout a new leaf. Would highly recommend.
