Was discussing this on a different thread. But now I really want to find an alternative to the skimmer I have. I have the RSK 300 which is very large and very loud even when i turn the pump down to 1%. It came with system that I bought and has some advantages for example it is controlled by an app. If you look at the specs for this skimmer this , it's really made the tank much larger than my 42 gallon/52 system. Does anyone have any good suggestions for a smaller skimmer that won't be so loud and take do much real estate inside the sump? Thanks so much otherwise right now what I'm doing is turning it off during the day because it's just too loud. Look at the size of that thing! it's turned off bc i want some quiet. I was looking at the octopus 150 model, but that looked also very large and doesn't even come with a pump?
