A: Hi, this product does not contain any elements that add CO2.

**Q: How do i know if i need Apt 1,2 or 3?**
A: We currently have APT 1 / Zero, APT 3 / Complete or APT E /Est. Index in our fertilizer range. 

1. If you are just starting on a new tank, it is easier to start on APT1/Zero and then move to APT 3/ Complete when you have more plants.
2. If you have a planted tank with a lot of fishes, APT 1/ Zero is more ideal as it does not have nitrates.
3. If you have a grown-in tank with more plant load, APT 3/ Complete is ideal for you.

### ⭐⭐⭐⭐⭐ Review
*by S***. on 1 February 2024*

Complete plant nutrition in a totally non clouding formulation. Includes a graduated pipette for precise dosage relative to aquarium capacity. Does not cloud the water at all, and produces dark green, rapidly growing plants. Very highly recommended. A very small amount produces truly amazing results. Had no effect on our fish.
