This is interesting and kind of goes back to a post I made a little while ago - I leave it with PH's, heater and salt for weeks at a time. So far it's served me well, and ensures if there's an emergency, I can dip right in and have premade goodness ready to rock. I've left it up to about a month and a bit when things go a little insane, and so far no issues as long as the temp and salinity match
