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.

5.0 out of 5 stars Live Plants Love This Boost!
Reviewed in the United States on January 30, 2023
I purchased the API Co2 Booster Freshwater Aquarium Plant Treatment when I noticed that I had an active algae overgrowth indicating an imbalance of nutrient in the tank. Since the tank is fairly small, and I don't have an external CO2 pump, I thought I would give this a go. Within a week of following the dosing directions on the bottle my algae problem was significantly reduced, and my plants began a completely new growth cycle. Now a few months after using at a regular interval things are looking healthy and lush. A small bottle goes a long way, and so even though it is a bit pricey, it has been completely worth it! I would definitely recommend for any kind of live plant set up.

I've been using this for a month. I have noticed a small, difference in the plants. But not much. I dont use CO2 directly, this is only used as on its own. My star rating is neutral as I cannot see any significant changes in my tank.
