10 days into vacation, both tanks looked fine until yesterday.
I noticed the Red Sea ATO filled up a rather large amount of water yesterday (timed out after a while), and another round today.
Simple reason was that the skimmer overflowed while lights were turned off. This led to the 5 gallon skimmer container to reach the skimmer sensor water height which turned off the skimmer (great job Hydros).
I only had the sensor at the 3.5 gallon mark so still some room to raise the sensor up (manually). Also. lowered the pump from level 4 to 3 of the VarioS4S, and lowered the water level in the skimmer from 2 to 3. Lastly, will add another 4 gallon of fresh saltwater over the next few days. All of this was done by the person who does the fish feeding.
Seems like I should have listened to
@dangalang who recommended to run the skimmer more dry. I did test it though for a couple of weeks before going on vacation and it seemed fine. And something happened in the tank overnight, which caused the skimmer to overflow suddenly rather than gradually. Maybe there was some massive snail or urchin spawning, etc. Did not think of this before tbh.
Otherwise, tank seems great, I can still see through the windows from all sides which surprised me.
