Got home today from work and noticed that my Xenia was not open as much as it usually is. I also found some spots on it that resemble mold to me. I did a water change yesterday(25gal in a 120gal) but everything checks out. I did the change to get my Ca. and Alk. back in balance, my Ca was at 520ppm and Alk was at 11.7dkh. Now its down to Ca 425ppm and Alk 8.1dkh, was it too drastic of a change? I've heard that water changes are the best way to get things back in balance.
Thanks,
Rich
