Description

API ROOT TABS Freshwater Aquarium Plant Fertilizer promote strong roots. Without proper fertilization, aquarium plants gradually yellow, drop their leaves and die. Aquarium plants require essential nutrients for vibrant growth. API ROOT TABS for freshwater aquarium are formulated to supply key nutrients, including iron and potassium and carbon, to help new aquatic plants get off to a vigorous start and to keep established plants flourishing. These nutrients are consumed over time in the aquarium and must be replenished for plants to thrive. Add tablets monthly to ensure best results. API ROOT TABS are safe for use with tropical fish. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium.

They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your tank. Make sure to use all products as directed in order to ensure the best results.

  • Great product
Size: 10 Ct (Pack of 1)
I always use these and never had a problem. My plants grow so nicely and so easy to put in not to big and a great price.

  • Good for leaves
Size: 10 Ct (Pack of 1)
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!

  • Seems to work, don’t like crumbling
Size: 10 Ct (Pack of 1)
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.

  • Great but
Size: 10 Ct (Pack of 1)
Plants thrive, the fish like to explore the tabs as the dissolving occurs.

  • Crumbly
Size: 10 Ct (Pack of 1)
These things dissolve as soon as they hit the water. You have to mad dash to shove them into the soil, but you still end up with a cloud of fertilizer in the water, and white particle dust all over the place. You end up feeding algae as well as your root plants. It's a bummer to have to do a water change every time you put these in the aquarium. ... show more
