API ROOT TABS Freshwater Aquarium Plant Fertilizer 0.4-Ounce 10-Count Box

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.

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!

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.

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.

Plants thrive, the fish like to explore the tabs as the dissolving occurs.

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.

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.

Must Have if you are growing plants..

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

Happy with product will purchase again! Thank you

Used for a boost as plants were looking a little dull and I don't have a fertiliser base under my substrate, they perked my plants right up.

Very useful for planted tanks

Great for your live plants in an aquarium
