KH "Used Up"
The KH in my tank drops FAST. I am not too sure what would be using it up at high rates.
3-4 days after water added
Mon. Under 1 KH added baking soda to reach 4 KH
Tue. Not Tested
Wed. Not Tested
Thu. Test before w/c Under 1 KH w/c added baking soda to reach 5 KH
Fri. Not Tested
Sat. (Today) 2 KH... Going to do water change today not going to add baking soda no point.
More curious as to what would cause this drop?
