Son I have the ADI kit but it may have expired it is from 2006. So I heard about the tetra 6 in 1 test strips. Are they just as good? They have a great rating on Amazon.
IME strips are "almost" as accurate as API liquid tests, but not quite. They sure are fast & easy. I used to split the strips in half the long way to reduce costs...How cheap am I? Yeah, that cheap, lol.
Even in my cheapness I would not expect accurate results from a 12 year old test of either type. Time to buy new!
