rabbitoid spotted that I had mistakenly set them up as 2 day ponds instead of 7 day ponds from March onwards, and was kind enough to let me know. It's impossible to change the days/move after creating a pond (and rightfully so). I figured there's at least a remote possibility that others signed up thinking it were 7 day ponds too (like myself ;)), so I decided to delete the ones were I made the mistake, and recreate them with 7 days. 

I'm sorry for the inconvenience this causes for those that had already signed up. Please sign up again :)
