Water changes won't bring your pH down or for that matter change your pH at all hopefully. Your tank will generally be the same as the tap water you put into it. So I'm guessing your tap is 7.6 pH also. If it isn't then something in your tank is causing the pH to either rise or fall (if we are only talking 7.5 compared to 7.6 for example, then it's not a concern). That being said, there is nothing wrong with 7.6 and most of the tropical fish out there will just love that pH with little need to
acclimate to it. Were there any specific fish you were looking to get?
Congrats on the cycle by the way
