## Questions & Answers

**Q: Can this be used along with co2 supply? Will this be useful to kill algae?**
A: This is not a algea killer, Is your tank newly setup? If its newly setup tank, you will get algea as the plants or unused nutrients in water will promote algea growth.  If you have a planted tank, the plants will grow and use up the extra nutrition and soil will also lose nutrition and algea will stop 

atleast in my personal use, this product never prevented algea. If you have fish in your tank, you can try this, however best cure for algea is constant water change

**Q: What dose it means start up, change water n adding fish?**
A: No, it is for liquid carbon adding to planted aquarium for the purpose of photosynthesis. 

For startup you need to get API quick start, stress Zyme and stress coat

**Q: How often should i use this for my moderately planted 30 l tank**
A: Don't buy. This is not CO2. Simple algaecide. Will kill all moss and anubias

**Q: I do not have a co2 system,can i use this just by itself to help the carpet plants?**
A: Hi,
This is a meant to be a replacement for CO2 system, so you can use this even if you do not have a CO2 system installed in your aquarium.

### ⭐⭐⭐⭐ Good product...seeing significant improvement in plants growth!
*by K***N on 29 June 2017*

Been using it for more than a month. I am definitely seeing good improvement in the plant growth. I have a 4ft planted tank with all essentials of a planted aquarium but no CO2. Would highly recommend this product. As always with planted tanks have to be a little patient.
