    • Works as it should
It doesn't leak it's a good value for the buck it's concentrated so it goes a long ways for a small bottle easy to use and the plant growth is steady and seems a little greener than usual

    • Put This In Your Leaf Zone
I apllied this to MY leaf zone......Get it? Otherwise, this is my goto when it comes to aquarium ferts. With the API name behind it you have the guarantee of quiliaty and precise measurements. Works wonderfully, plants are super healthy and I could see them green up a bit within a week. Came sealed as with all API products and had that good smell of quality assurance. ... show more

    • Aquarists need this, Horticulturists as well.
It does its job of removing chlorine and chloramines from the water. An undeniable essential for aquarists, and in my opinon, for anyone who wants their potted plants to thrive as well. I have a drip watering system that draws from a bucket of mostly tap water, and my potted fig trees have absolutely thrived since I started treating their water with this dechlorinator right after I refill the bucket. Remember, even though chlorine will evaporate in @ 24 hours, chloramine will not. Do your fish and plants a big favor, treat their water to eliminate the chloramines. ... show more

    • easy to measure, easy to use
It seems like it worked great. Gave the plants in my new set up the boost they needed to get along early in the process and continues to deliver a very lush beautiful planted tank.

    • A Great Source of Iron and Pottasium.
My plants have been very happy with this safe and nourishing formula. However it doesn't provide all the necessary nutrients so its great when paired with another fertilizer like Seachem Flourish

Best and safest for shrimp and snails if in your tank I’ve never lost any using it plus it comes with its own measuring lid so it’s easy and simple to use!
