I purchased my Red Sea 300 about 4 months ago now, and I have had nothing but issues from it. The ATO sensor wasn't working, so I got a new one from Red Sea and that one still doesn't work, the ATO pump ran dry the whole night without turning off or a single notification to the app, the magnets in the wave makers aren't strong enough to really hold onto the tank (mind you I bought the MAX setup because the gear was "designed" for the tank), the "smart" protein skimmer doesn't do anything in terms of adjusting the pump or the skimmate levels. The list is far longer than it should be for a $4,000 setup. I thought Red Sea was supposed to be "premium"?
