I am having trouble with finding a skimmer for my Reefer 170. I first tried the Simplicity 120 but had nothing but problems, and the noise was too loud, especially for a DC motor. Then I got a Octo 150 INT which I love because it’s very quiet and reliable, it just seems oversized for this water volume. I just can’t seem to dial it in properly. Any recommendations? Must be quiet as it’s in a home office right next to my desk.
