API Root TABS Freshwater Aquarium Plant Fertilizer 0.4-Ounce 10-Count Box,Tablets

Very useful for planted tanks

It's been 1months and the plants grows perfect but I can't say it's only because of this API root tab. I've added ADA bottom plus & seachem Flourish root tab as well, along with EI liquid fertilizer dosing. With this different root tabs my plants grow so lush and fast as well. Please don't rely only on single company root tab, add more other company root tabs for best result. API root tab is good and please watch review and research by your own. Thank you API through amazon.

Using it. Used twice in a month. Not sure about benefits yet

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!

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.

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.

product works well well combined with api leaf zone, please note if your aquarium is heated they will start dissolving much more quickly so you want to try to get them in the substrate fast. Once I adjusted my light cycles and used this product I saw an instant growth and healthy glow in my plants.
