## Questions & Answers

A: Correct answer is 5ml for every 10 litres

**Q: Why in description says use 5ml for every 10liters if on the picture of bottle says 5ml for 10 gallons? Thats a big difference**

**Q: Is the colour of this liquid blue??**
A: Hi,yes the colour is blue but the colour disappears when put in your tank. BOB
