I live in Colorado where high pH is the norm. My 40 gallon tank's pH level has slowly been dropping. It had been 7.8 since I got the tank and set it up. Over the past week it's dropped to 7.4. Yesterday the pH was 7.4; today it was 6.6. Should I be concerned about this? If so, what should I do? Thanks in advance for any replies. Oh, and I haven't changed anything - food, chemicals, etc. are all the same as usual.
