yes, check your tap and then let a sample of tap water sit for 24 hours and check the pH of that.
Most will tell you, pH is not so important as long as it is stable.
My pH is about 8.1 out of the tap and I just do 2/3 tap and 1/3 RO aged in a barrel and then right into the tank.
The important thing is what is the change between right out of the tap and letting it sit for 24hrs. There is often a big swing between the two and that will cause problems with every water change; your pH will keep bouncing if there is a big difference and you don't age.
Breeding is more of a big deal with pH than a show tank.
Keep things as simple as possible. If you have to mess with RO and remineralizing, etc .it complicates and makes things more of a chore....and if you are like me the more of a hassle the more I don't want to do it. Then your fish start to suffer.
