api plant leaf zone root tabs co2 booster fertilizer planted aquarium aquatic plants

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.

I was told at the fish store that I have the exact opposite conditions for growing plants. I don’t have the proper substrate, lighting, and I have a tall tank making lighting less ideal. Idk cuz this is my first aquarium and never planted anything before. I’m giving the root tabs credit. I broke small pieces up and used giant tweezers to shove them under the plants. The dwarfgrass is new so we’ll see how it does. Most of the plants are beginner, hard to kill kind. My son planted some Ludwiga (red one) in his own tank the same day and his looks sad and barely grew compared to mine.
