    Hi Tom, I'm helping a friend of mine to find out how to reduce the pH of his newly built fish pond. The pond was built using the normal brick & cement used in building construction. It had been more than 3 months & the pH remains at around 10. Thanks in advance.

    Well cement uses Lime, which will buffer to a pH 10.

    He needs to drain it, then add a good pool paint coating over that of a liner.
    Reducing pH will eat away the cement.

    Typically a marine grade epoxy paint is used or "pool" paint.

    Several coats, so it's not that cheap.
