Hey Reefers, I recently bought a Smart ATO Micro brand new from my lfs. Now, everything is setup correctly. The problem I'm having, and I don't know if it's the ato's fault or something else. But whenever I go to check on my water level in the sump, some times the level will be above the optical sensor. My tank is a Nuvo 25g Lagoon. Any help is much appreciated
