I just want to share a lesson I just relearned. My protein skimmer drains off about a quart of water a day. Add to that the evaporation, and I was topping off about two quarts a day. I got lazy this week and didn't check my SG. Bad move! My SG went from 1.021 down to 1.017. My tank is FO and the fish don't seem to be distressed, but 1.017 is a bit low for my likings. I'm in the process of doing incremental water changes over the next few days to get my SG back where I want it.
So for you newbies and old dogs relearning like me, keep an eye on the SG and don't get lazy.............
