    I did a 10 gallon water change. Basically cleaned out my sump. It was time for one anyways, so nothing too drastic.

    I used distilled water and Instant Ocean salt. I stuck two 1400 GPH powerheads in the mixture for a few hours and tested the salinity with my refractometer often. The salinity was 1.026 (tank was 1.025), so it should raise the tank salinity a tad, but not too much as to stress anything.
