I've been running this ATO for a few months (May sometime), and the pump is just terribly loud. I can't even accurately describe the noise, but it's horribly loud - I can hear it across the house. I've tried shaking the pump to see if there's air trapped inside - no relief, it is suspended in the reservoir - the nature of the tubing and cords just make for that scenario anyway. I also noticed that the thin plastic stem that connects to the flex tubing was cracked out of the box. Would that contribute to the noise somehow? I wouldn't think it would, but I don't know. I've tried adjusting the flow rate too - no joy there either.
I'm upgrading tanks in the very near future, I'd like to incorporate the ATO into the new build, but if I need a replacement pump, or the adapter to use a different pump, I may go another route altogether. I've been using Tunze products for years, very disappointed in this little pump. Any help or advice is greatly appreciated.
