    This question is for all the 3reefers who purchased the Hanna Checker Phosphate Photo Meter.
    How do you like it?
    Was it easy to use?
    Do you feel it was accurate?

    I purchased one but the jury is still out. When I tested my phosphates with the Hanna checker, I got a reading of 1.07. When I tested with my API test kit I got what was my normal reading of 0. I might be doing something wrong with the checker, not sure. Have any other 3reefers who purchased this product have a similar experience?

    I don't have a hanna meter (I use milwaukee meter), but I think that reading is too high (unless you got some serious algae problems now).

    make sure you dissolve all particles in the cuvet before measuring. even a small undissolved particle can affect the reading.
