cbashaw December 11, 2013 Share December 11, 2013 I am going out of town for 3 weeks, and want to let my tak cycle while I'm away. I'm using all dry rock. I have a heater and powerheads in the tank. Since I'm only using dry rick, and there is no livestock, will I be ok not setting up an auto topoff. As the water evaporates the salinity will rise, and I will need to adjust it when I get back. Can I get away without topping off if I set the salinity a little low before I go, or do I need to setup an ATO before I go. Link to comment Share on other sites More sharing options...
