    Well thanks hope you can help me out now, I just did a 1 gal water change in the 12g nano, and I add some alk buffer about 2 ml, then after testing with API, shows 10kh and with a very old salifert shows 6.4 , both tested 2 times, Ca is at 380 and
    Po4 shows between 0.0 and 0.25 in the color chart
    So I'm a little concern , corals don't look very happy.
    Thanks
