Up and until now, I used nothing but the euroreef, I one on the eel tanks of the type of design model that runs no matter what and the euro reef model that opens with a full twist off to clean the skimmer cup are acting funning like for each time there be a slight power flicker for even a second, the pumps on the type of model not restart again without my helping it and being that im more busy with my family, I cannot be here every time when that happens and I need to feel secured about the skimmer in place. And I thin k I will do just that, look in RC at larger reef tanks with the AC.
