Designed for freshwater tanks with tropical fish, these tabs help prevent yellowing and leaf drop while supporting vibrant coloration. Compatible with liquid fertilizers, they also aid in reducing algae by fostering healthy plant competition, making your aquarium a thriving underwater oasis. ## Description From the manufacturer Without the addition of essential nutrients, aquarium plants will gradually yellow, drop their leaves, and eventually die. Plants take up nutrients by their roots and leaves. API LEAF ZONE plant fertilizer contains an excellent source of the necessary plant nutrients and is rapidly absorbed through plant leaves to promote lush growth and vibrant color. 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. Vibrant aquatic plants vs. unsightly algae Healthy growing plants can outcompete algae. In fact, aquatic plants help reduce algae growth, as they compete for the same nutrients. Here are some guidelines to set up the right environment For thriving aquatic plants, use a lighting system type and wattage that suit them best. To prevent unsightly algae growth, aquarium light should be on a maximum of 8-10 hours per day. It is recommended to test the water with both API NITRATE & API PHOSPHATE TEST KITS because excess nitrate and phosphate can contribute to unsightly algae growth, and zero levels of nitrate and phosphate will hinder plant growth, so you’ll want to make sure levels are optimal. To get rid of algae, use API ALGAEFIX algae control at first sight. API plant products are formulated to be used in aquariums containing freshwater fish. If overdosed, perform a water exchange to remove excess material.

Review: Water changed to Orange/Brown - 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 Review: Wow! Noticeable difference within a week! - 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! ## Features - API ROOT TABS plant fertilizer promotes lush growth of aquarium plants with ingredients such as iron, potassium, and carbon that help develop strong roots and promote vibrant growth. - Without proper fertilization, aquarium plants gradually yellow, drop their leaves, and die. - API ROOT TABS plant fertilizer are formulated to supply key nutrients to help new aquatic plants grow and keep established plants flourishing. - These nutrients are consumed over time in the aquarium, and must be replenished for plants to thrive.

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 T***A on 6 June 2022* Not sure how it will work on my plants but it did make my aquarium water cloudy and brown.
