There you have it. We hope we have provided some tips on helping you select the right aquarium plant food. Keep in mind that even with the same product, the result could be different for each individual due to there being many different variables. Tank size, plant species, and water quality to name a few. Here are some factors to consider when you purchase aquatic plant food.

1. Fish-safe Food

First, make sure the plant food is safe for the fishes. Most aquarium plant food should be safe-for-use as long as they don’t contain any harmful chemicals. That said, you should always take precautions and start off with applying smaller-than-required doses of plant food. If you don’t observe any strange behaviors from your fishes then you can start to increase the doses of plant food to the required amount.

2. N-P-K Ratio
The N-P-K ratio refers to the balance of nitrogen, potassium, and phosphorus in the fertilizer. You can learn more about it in this article. Plants are going to require different levels of these three nutrients depending on their stage of growth. Most aquarium plant food should be labeled with a ratio. A common example is 0-0-1. This means the fertilizer contains 0% available nitrogen, 0% available phosphorus, and 1% available potassium.

3. Liquid or Tablet Fertilizer
Aquarium plant food comes in several forms. The most common are liquid fertilizers and tablets. There are a few factors to consider when picking the type of plant food. For example, if you only have a few plants in the tank then the small tablets may be effective. If you have a forest of plants then it may make more sense to use liquid fertilizer to ensure the plant food is spread across the whole tank. There’s no major right or wrong answer. You may need to do some testing on your own to find out which choice works better for your aquatic plants.

With the above factors in mind, here are some aquarium plant food choices to consider getting.
