What is raising my pH?
I've just cycled my new tank. I tested the parameters, and ammonia and nitrite are 0 and nitrates were about 5ppm. I also tested pH and it was 8.2. I tested my tap water ph however and it comes out as 7.5. Any idea why my tank's pH is much higher?
The fish in there stills seem pretty happy right now, and I know that fish can acclimate to changes as long as they are gradual, but I'd like to gain some insight on what is possibly raising the levels. Thanks!

Maybe its from my substrate? I read that crushed coral could increase pH? Should I change it?

Crushed coral and slate will raise pH. Change it if you're not planning on stocking alkaline-loving fish."Somewhere, something incredible is waiting to be known." Carl Sagan

Crushed coral will leach out calcium (and other minerals) when used in fresh water aquariums which will cause you pH to climb. Same thing applies to marine substrates when used in freshwater tanks.
I would suggest changing your substrate as well
Just make sure you don't put your fish though drastic pH swings through the processIf you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

What kind of fish do you have? For instance, if you have an African cichlid tank, that ph is actually good.
