I have a Red Sea reefer 250 and am new to saltwater. I understand the function of the Auto top off and everything, but how does it work and where exactly is the water supposed to drop from on the Red Sea ATOs? Mine drips about once a second from the white piece on the right side close to the reservoir (white piece seen in picture 1). Is this correct? I am also able to twist this white piece to either increase or decrease the drip. It seems like it is where it is supposed to drip from, but I just want to make sure. -Any help would be greatly appreciated. Thanks!
