Hey all,
As I am struggling to piece together ideas for a potential new saltwater setup, I stumbled upon a small issue I'd like to get your feedback on. Currently, I'm leaning toward a 6g long with a second 6g long as a refugium sitting at a staggered height behind the main tank. Because of this setup, I'm pretty sure I'll need to have a float switch or ATO sensor in the main tank versus in the fuge. My thinking is that since the fuge is at a staggered height, I'll be using a powerhead from the main tank to push water into the fuge then a large bulkhead will drain back into the tank. In doing so, I think that the water level will remain constant in the refugium while the main tank will fluctuate. If that's accurate, then I'll need to place the ATO sensor in the main tank. So that brings me to my question, with a high level of surface turbulence is there a compact ATO that isn't going to trigger falsely as the ripples in the current fluctuate the height of the water? Maybe folks have other thoughts for an ATO design/option that might work better?
Any feedback is appreciated.
