Good stuff
These worked really well in my planted aquarium, it's been over a month and the plants are all looking green and growing, would definiely recommend and would buy again as needed.

Good for leaves
I cannot recommend these enough I put an entire pack in my 20 gallon next to all my dwarf hairgrass and within 2 days they all sent out runners that are already poking through the gravel, supports healthy, non yellowing plant growth, they do make the water a bit cloudy so put them in fast!

Green plants
Plants aren't dead, so I'm assuming it working. My plants are nice and green days after finally planting them in sand substrate. They're a little expensive, but I'm glad I bought them to get a jump start before I switch to a liquid fertilizer.

Seems to work, don’t like crumbling
Seems to do it’s job! I don’t like that the tab immediately starts dissolving the second it touches the water, so you have to be quick putting it under the sand.

Brought my aquarium plants back to life!
Brought my Amazon sword back to life! Definitely recommend it. If you have a big tank I would recommend getting two packs. One was enough for my 20 gallon aquarium.

Starts melting as soon as it touches the water
Maybe I got a bad batch but these root tabs start melting as soon as it hits the water, then turns into a cloud of fertilizer as I try to push it mid way into a sand substrate. The cloudiness clears up after a few mins but I wonder how much of it made it into the substrate and not in the filter.

Perfect for aquarium plants, and priced well
Great for a planted aquarium. These really get the plants going good with lots of nutrients. Just beware of over using them or you will have an algae issue that is hard to fix. I used these for amazon swords mostly, and they grew right out of the tank and the plants became very full and lush.

Works just like it's supposed to!
These worked great for my plants. They just weren't growing until I used these and now they're growing like crazy! They're now taller, fuller and have brighter color. My aquarium is looking fantastic!

Not sure how it will work on my plants but it did make my aquarium water cloudy and brown. I have changed half tank water the next day after using this tabs. Hopefully cloudiness and discoloration will go away and won’t effect my fishes. Won’t buy it again
