| Yes, stream is good for collecting debris, and need cleaning. I clean mine 4 times a year, but I only average 4oz of feeding daily. I routinely pickup leaves and other junks from the stream everytime I walk around it. I may add a BB to the waterfall, and see if i can readuce the cleaning to once a year. (see, I am way lazy). In the summer, I had to clean my filter, I mean deep cleaning, every 3 days due to koi pooh piling up. Thing did not change much after I shut it off, when I shut off my waterfall, water turned green in 2 days, so my main filter is pretty much a non-filter, and my waterfall has been my main filter.
My pond is netted, no leaf in the pond.
My water quality is so-so, kois have been growing like weeds. except for a couple of kois who refuse or too old to grow, most of my kois grew 14" or more a year in this pond. |
