Raise pH?

[Louise02]

I have a five-gallon aquarium that will house a betta soon.  The pH is down at about 6.8.  I have added a bag of crushed coral, cleaned filters, and changed the water.  I don't want to push the pH too quickly, but is there anything else I can do to try to get the pH up to 7?

 

BTW, I did add a wonder shell.  I wasn't going to dissolve much of it in this tank, but I thought that I would add a little bit of mineral.  We have been using RO water, as our city water has both chlorine and ammonia (how is that even legal?).  I don't know if this is a terrible idea, but snails have had a hard time keeping healthy shells in this aquarium in the past.  I was thinking to just up the mineral a tish. 

 

Thoughts?

Add some crushed coral to your filter. Put it in a filter media bag and place behind media. That helps with water hardness for you snail especially. Or add more to gravel @Louise02

Yes, cloramines are common in tap water.

I just starting using Salty Shrimp GH/KH to remineralize my RO water for my shrimp tanks.  Ran it through my test kits and it seems to work very well!

Why not use seachem's pH neutral regulator or alkaline buffer? To sharply raise hardness, try equilibrium.
