So, do you feel that there is a certain temp this occurs? In So Cal, several hobbyists have had the most problem at 60-65 degrees. Our water rarely goes below 50; in fact this year mine never did. It was a cool winter and the pond stayed 51-53 for well over a month. I started feeding about 3 weeks ago at about 55 degrees. I am now up to once a day and the pond reads 59-61. I do expect it to rise the next several days.
Because you folks "in the cold" go colder, does that change the alley? I realize that there are many factors, but is there evidence that certain temps favor the bad bugs over the good? Inquiring minds...
