API ROOT TABS plant fertilizer are rich in iron to develop strong roots, rapid growth, and best coloration. Slowly releasing simple carbon compounds, API CO2 BOOSTER product aids in fueling the photosynthetic process by turning light energy into new plant growth.

## Questions & Answers

**Q: are they copper free?**
A: yes. no copper. api has a phone number you can call for more info. i have found them very helpful when i had questions.

**Q: My tank is 30 gl I need use how many tablets?**
A: The instructions say you should use 1 tablet for every 30 square inches of gravel surface area.  Most 29 gallons are 30" x 12", which is a total of 360 square inches.  Divide that by the recommended 30 square inches per tablet and you will need to use 12 tablets for the aquarium, once per month.  Of course, that's providing your aquarium is 30" x 12".

**Q: i have a 20 gallon tank, can i use theese with the liquid c02 booster and leaf zone or flourish excel?? or will i be adding to much.**
A: I use them with leaf zone and flourish Excel... no problem so far...I do not treat the whole tank with this tabs... I only add them to specific plants that need more nutrients such as my aponogetons ( bulbs)

**Q: I need use how many tablets for 30 gl?**
A: I put all 10 inside a 60 gal. I guess just put 5 for the 30 gal.

## Customer Reviews

### ⭐⭐ Water changed to Orange/Brown
*by  on Reviewed in the United Arab Emirates 6 June 2022*

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

### ⭐⭐⭐⭐⭐ Wow! Noticeable difference within a week!
*by  on Reviewed in the United States 6 May 2023*

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!

### ⭐⭐⭐⭐⭐ Make sure put deep to stop them clouding tank otherwise good so far
*by  on Reviewed in the United Kingdom 5 November 2025*

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.
