## Questions & Answers

**Q: Is this good for African cichlids**
A: This can be used in aquariums or ponds.  But i am surprised you need to lower your pH for African Cichlids.  Of course this depends what your pH is but keep in mind that rift lake fish need a pH higher than neutral.

**Q: Is there any difference between this an their smaller bottles used with aquariums? Other than the amount?**
A: It is the same product. The amount you need depends on your tank size(s). Some people just have a small aquarium in their home while other people have 3000 gallons of fish tank. 😉

**Q: Why doesn't it say anywhere how much water a bottle of this can treat?**
A: A 160z bottle can treat 4730gallons of pond water.

**Q: what is the difference between the two products Ph down for ponds and ph down for aquariums? Are the ingredients and strength the same?**
A: The PH is dropped regardless where the body of water is. Pond, pool, aquarium,  fountain ask the same. Just pay attention to the correct dosing for the volume of water.

At first I didn't think it worked at all, but then discovered that my test strips were expired and not working any longer. I got new pond test strips, and the pH and Alkalinity are perfect!
