## Questions & Answers

**Q: How long after using do you re- test to see how much the pH went up?**
A: We would recommend waiting about a half-hour in order for the water to fully circulate so that you get an accurate reading. If you have a very large system or very little flow, you may want to wait 1-2 hours. You are safe to re-dose at that point as long as you have not changed more than 0.2 in pH, which is the maximum we recommend changing within a 24 hour period to reduce fish stress. If you have any other questions, feel free to reach out to us at 1-800-847-0659 or APITechServices@effem.com

**Q: Can this be used in a tank with invertebrates?**
A: Yes. Many years ago this was labeled for ponds

**Q: This should be fine for a Brackish tank?**
A: You can use it however the KH of a brackish tank might prevent you from lowering the ph.  Please contact API at 1-800-847-0659 and we can help.

**Q: does this come with both ph up and down? Or just one of the two?**
A: Just one bottle,ph up!
