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.

  • Best root tabs for aquatic plants
Size: 10 Ct (Pack of 1)
I started using API root tabs a few months ago since they are safe for shrimp. I did notice from day one how my plants started to grow so quickly and bushy. It made my plants healthier. The roots grow pretty quickly and big from cuttings. I feel this is an amazing value for your money.

  • 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!

Noticeable difference in plant health. Almost immediately released its nutrients be for it got in the ground though.

  • Good so far
Size: 10 Ct (Pack of 1)
my plants seem to like these root tabs and they are very easy to slip into the gravel. I also like that they are easy to break in case you want to spread it out. These seem to dissolve or at least start dissolving as soon as they hit the water. I would say this is pretty good value for money.

  • Good plant support
Size: 10 Ct (Pack of 1)
Works great. Make sure to push into the gravel or substrate quickly to avoid the pills from disintegrating in the aquarium. My plants have shown good results from the root tabs. I would recommend.

  • 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
