Sealing bricks

Mine came from bunnings too!! They raised the pH through the roof, and I'm not sure if it's because they're broken, or what, but I want them to not hurt my fishies!

Looks to me like it's because they're concrete blocks, not normally inert clay bricks. Concrete will raise the PH a lot.
