I have a 9x4 foot 400 gallon pond with a 20 gallon tupperware and green scratchy pad filter. Over winter, I plan on draining the filter to avoid freeze issues. However, won't that effectively kill the bacteria that have built up there? Will the pond have to cycle again during the spring? The filter is buried in earth/rocks, so removing it and keeping it running indoors isn't an option.
By the way, when did the forum change its appearance? I dislike it very much. I find that it's very helpful to see everyone's pond size and experience in their signatures.
