## Questions & Answers

**Q: How many gallons does this 600 grams treat?**
A: I HAVE A 55 GALLON AND IT WORKS GREAT BRINGS UP THE PH WITH NO PROBLEM WHEN THE WATER US YELLOW PUT IN TWO TEASPOONS AND IT DOES THE JOB

**Q: How long does the desired ph last in the tank? A day ? A week ?**
A: Hard to say, I did a 20% water change every week. This product makes the water higher in pH.

**Q: Does this need to be used at every water change or top off??**
A: I use it after water changes but I always check the KH of the water before adding the product. It is very powerful stuff so I suggest following the directions on the back. I try to keep my KH around 4-6 along with my GH. I would not put this in every time you top off.

**Q: I used too much seachem alkaline buffer and now my kh is too high. how do i remedy this other than a water change?**
A: You could add Seachem acid buffer to bring it down.  Most use the two together to get to correct alkalinity & ph desired.  See Seachem website for amounts to use if both buffers.
