I have planned on putting a portable shelter over my pond this winter. It is one of the Shelter-Logic items which has a dark cover. My thinking - to make it easier for me to see what is going on and checking the de-icers, etc. when there is a lot of snow.
I recently read a Koi-based article which declared the fish need the sunlight, even during their hibernation time. The basis was that it gives the Koi a couple more months of grow time. (?)
What does that mean to all the people who put their koi into a cold garage or cover with a solid tarp?
Does anyone have any thoughts on this? I still could use the same frame and put visquine as a cover instead of the dark cover. Not happily, but I could.
