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

I bought these for a red tiger lotus in my betta's tank. I'm using stratum as substrate which isn't providing nutrients to the plant. You can see in the first pic that the leaves were tiny and really pale...almost translucent. I put a root tab under it and after a week I had big red leaves coming through. The second pic is about two weeks later and I'm just blown away by the color and size of the leaves now. It's amazing seeing the growth with the root tab added. I've got a 10 gallon tank and only two root feeders so I'm only using two tablets. If you've got a heavily planted tank it says to use 1 tablet for every 30 sq. Inches...so it would take 6 tablets to cover all the substrate in a ten gallon. Idk how often these will need replaced but for my purposes of only a couple plants needing them, it's a great buy and really happy with the results I'm seeing. Third pic is another week later and this thing is really showing itself now. Only thing I did to make it go from small and translucent to big and red is add a single root tab under it. Very happy with results!

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.

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!

Super potent. Don’t follow directions. One or two per 10 gallon tank. I almost tanked my water nitrates with over putting it in since I have all live plants. They do work. Plants look great. Even my semi aquatic plants grew more root buds. But I have had to do more water changes to get everything stable. They melt fast before getting into substrate. So it made my water very milky which in that respect released a crap ton of nitrates into the water. Size is about the size of a Tums.

REALLY WORKS MY PLANYS ARE THRIVING. ITS CHEAPEST HERE AND PETSMART. 9.99

The tablets are unstable as soon as you put them in the water. Dissolved instantly and turned the water chalky white. I would not purchase unless you get a different lot and company says that they will not fall apart before you can place them under the gravel.

These were great for my plants in the tank. I noticed a huge difference right away! Very effective. Will be buying more in bulk.

Seem to work as described, stay under the substrate and benefit the plants.

Was bit skeptical about these specially with some bad reviews however having planted aquarium I need something for my plants to thrive. At first when I put them in yes they start to dissolve so have to be quick but then noticed my tank started to go bit cloudy. Got up this morning and my tank has cleared up know these don't work fast but hopefully my plants will start getting something as my swords leaves are starting to curl. I did use once before the liquid from a pet shop and sent my nitrites and nitrates through the roof which did kill few my big clown loaches and endlers. These are good if read the instructions I dug mine about an inch so that's prob why I had some clouding,but so far so good in my tank now I have lemon blue eye bristlenose and blue pearl shrimp and as said they still alive.

Amazing love this but pricy

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

Helps my Amazon swords. Does disintegrate soon once out of the pack so place in substrate quick.

Very useful for planted tanks
