Thanks cmor. I think so as well. This ATO is first on my list so i hope to get it soon.
For now though, i honestly don't mind manually toping off. Doesn't really bother me. But when i start getting SPS
i really want the ATO just so i know the SG
levels always stay constant. Ya know what i mean? I think this ATO unit isn't just taking the hassle out of toping off constantly, but also piece of mind if you have expensive and sensitive livestock that need constant water parameters to thrive.
