PH Dropping

My tap water has a PH of 7.4, but after it sits for a while the PH drops to around 6.2. I tested this theory by putting my tap water in a 5 gallon bucket and let it sit for 24 hours and the PH was the same as the PH in my tank which is 6.2. So I know it was nothing in my tank making the Ph drop. My current fish don't seem to mind the PH being that low but when I try to add fish they cant seem to take it, even after acclimating for an hour.

The tank has been set up for well over a year and this problem just has me baffled. What could be the possible cause of this problem and how could I fix it.

NH4 0
nitrite 0
nitrate 10

I tested the hardness of the water and the total hardness was about 12. I am keeping new world cichlids
I found the total hardness, my understnding is that total hardness is a measure of Gh and Kh together. Individually I do not know the specific gh and kh values.
I will go pick up a test kit tomorrow and see what the specific values are.
