I swear having multiple connecting ponds is way better, winter and summer. The upper ponds stay at the same level all the time and only the bottom level pond needs topping up every now and then. Just add water to the top level pond and the excess water runs down to the bottom pond and flushes and tops up bottom pond.
Good thing my ponds are easy care right now and I am so busy running after my mother day and night. This morning she called and could not remember how to turn on her TV. Usually the staff there do it for her in the morning, but somehow she forgot to ask... Then I have been so busy taking care of her old condo and fixing and cleaning, and finally just about done that.... and out of the five kids my sweet mother had, nobody could be bothered to help me move her or clean and repair her old condo.... so mad...
