When it comes to understanding how to use root tabs, you want to think about where they are being inserted.
Yes, it is important to have them go at least 4-6 inches into the gravel, but what about the location? Where do you want to make sure the root tabs are situated insider the gravel? Is there a specific location that works best?

Use Closest to the Hungriest Plants
Along with keeping the root tabs closer to the roots, you also want to make sure to target specific aquatic plants.

The hungrier plants are going to be the most demanding, so having the root tabs closer to them will yield better results.
Before starting, create a small list of plants inside the fish tank.
Which plants are known for being the most hungry? Which ones are not as demanding? Look to create this simple checklist, so you know which plants to target and how many root tabs need to be inserted near them.
Now, this doesn’t mean all of the root tabs go closer to the hungrier plants! You still have to distribute them evenly, but it’s best to insert additional root tabs closer to the hungrier ones on your checklist.

Replace Every 3-4 Months
Once you learn how to use root tabs, it’s important to become consistent.

By having a schedule, you are going to have a far easier time managing the aquarium plants using root tabs. Otherwise, it’s easy to get lost in the process and then watching your plants lose their vitality.
If possible, it’s recommended to focus on how well the aquatic plants are doing using root tabs. Are they staying healthy throughout the 3-4 month period? Are certain aquatic plants not looking as good as the others?
These are good questions to ask so you can change how you use root tabs next time. This can be something as simple as where you insert them into the gravel.
