ClariSea update: This unit went online back on March 15th of 2021 and I'm half-way through the FIRST roll.

And have not cleaned a filter sock since... well, let's just say I was never really good at cleaning filter socks or replacing them fast enough to make a difference anyhow. lol!
No issues to report. It's functioning as expected and I have yet to perform any maintenance on the unit. It auto-advances the roll and I hear it move a little, a few times throughout the day and can usually get it to trigger if I decide to scrape the glass.
Tank is doing well and I recently caught these two Astraea snails on top of the tiger conch... Warning: Kessil Shimmer!!
