I noticed the last 24 hrs my overflows to the sump were noticeably louder *again* (seems to be a monthly thing). And it does "surge" down. Tonight my son exclaimed how big the full moon was (lightbulb!) and it got me to thinking - could they be connected, and having a mini "spring tide" each month in the tank? I feel like that would be far fetched in my 180, but technically nothing is impossible. 
Thought I'd throw the topic out there - do YOU notice anything particular or special in your tank around this time that makes you scratch your head, or cheer for nature? :smile:
Love this hobby!
