## Questions & Answers

**Q: My reef system ph is 8.0 and kh is 6 where would my kh be maintained after using this product?**
A: I dose slightly higher in my reef then the directions. My k.h is 8.5 to 9.5 with Hannah checker every 4 days of dosing.

**Q: How many grams is needed to treat a 30 gallon reef tank?**
A: I believe for every 1 teaspoon it will raise the ph by .1 in a 40 gallon tank. Since my tank is 50 gallons and I needed it raised .3 I have been adding 3 teaspoons a week and it has been slowly climbing and corals are looking better. I have read that this stuff is very safe and is hard to overdo so I wouldn't sweat it too much

**Q: Can i use this to raise my ph in a fish only tank if it will be a reef tank in the next 1 to 2 months**
A: Generally it is best not to chase pH. Any increases in pH from using this will be very temporary, like hours.  Focus on maintaining alkalinity within the recommended limits and pH will settle where it will. pH depends on time of day, bio load, CO2 levels in your house etc. and may ultimately require a CO2 scrubber to maintain at elevated levels. 8.0 is sufficient for a reef tank, even 7.9. Primary goal for a reef tank is stability, and chasing pH is a recipe for instability.

**Q: Can it be mixed with the ATO reservoir for automatic top off?**
A: It could, but you will have to mix at least daily to keep it suspended in the ATO reservoir water.
