I recently set up a Red Sea 300 G2+ and was super excited about the Red Sea ecosystem. Unfortunately, it's been less than impressive, especially the ATO+. On paper it seems like a super awesome system, but in reality it isn't. In my setup, I've noticed that it doesn't do a good job at actually measuring the water in the return chamber. It'll dump upwards of 1 gallon of RO water in 15 mins and then go "uh oh, you're above the sensor" and I think it's because of how the probe reads the level. It can't read through saltwater, which makes sense, but because it just dumps water time-after-time it dilutes the water in the return chamber and therefore it's salty enough to turn the pump off. Eventually it does circulate and things level out, and then the ATO just says it's "above" the level for a few days before things evaporate and we do it all again.
Maybe mine is just finicky or I'm just whiny, but seems like a bit of an oversight by Red Sea to have this problem. Or it could just be my setup and combination of not running my return strong enough or whatever, but regardless it's a pretty annoying point of the Red Sea gear.
