Hi Zaffor
Thanks for posting this video, as I have been wanting to actually hear how loud the DOS unit performs AWC.
Have you prolonged the duration of water change intervals and has the DOS became less noisy? If you have another video with it running at a medium or lower speed, I would be very interested to hear how loud it is.
I would be primarily interested in the noise that it makes when performing 2.5-3 gallon water changes over an 8 vs 24 hour period.
I really like the Apex integration of the DOS, but the added noise could be a deal breaker for me.
I have three. They're pretty loud, especially at first. They've gotten noticeably quieter over the past few weeks, but at the higher rates, it's still very noticeable from rooms away with a closed cabinet.
