So many aquarium products overpromise and underperform but these tablets really work. Plants have just taken off. Love this stuff.

Product raised my ph and killed an entire stocking of fish. Don’t use. Probably has an application it’s good for, but aquarium use is not it.

I did not realize these were for large pond flowers so I chopped one tablet into smaller pieces and distributed throughout aquarium (15 gallon cube). The plants are doing great, and they became more green by the second day of placing tablets at root base of all plants in aquarium.

I ordered some aquarium plants online and although they were doing ok they just weren’t thriving after adding the fertilizer it was as if they were actually living . would recommend

didn't work for any of my plants, except my cryptocoryne. All my cryptocoryne lost they leaves, that never happened with using API roots tabs. Waist of time and money.

I just started a new tank. This works like a charm for my root feeders. They are pretty easy to push deep into the substrate so they do not leach into the water column and as a result they deliver optimal nutrients to rooted plants. I have placed a few around in my planted tank, and so far everything seems to be just happy and improved color. No crazy water parameter changes or anything weird. Given me confidence to try harder plants and will definitely buy this product again.
