Hi all. I have a reef octopus classic 152 and it’s quite noisy. I have hoses coming in from the outside for fresh air into the intakes and it makes it a little better but the noise is coming from the pinwheel mixing the air up. If I restrict the water intake it quiets down but that minimizes the skimming so don’t think that’s an option. Any suggestions other than getting a different brand? What brands would be equivalent and known to be quiet?
