## Questions & Answers

**Q: Will algae grow with just this product, light, and saltwater?**
A: Assuming you’re adding a heater too, yes

**Q: My sandbed is 1”. Is it okay to add this to an established tank with fish/coral?**
A: I really don't recommend it.  It will cloud the tank severely and leave a powdery covering on everything.

**Q: Will this really cycle a new tank instantly? Seems too good to be true.**
A: Nothing, I repeat nothing cycles a tank instantly

 This will help kickstart a cycle but requires an ammonia source and time.

**Q: Do you have to add anything else to tap water to make this fish safe?**
A: As long as you don’t have any live stock you can just add tap water I would personally use dechlorinated water
