My neighbor's koi pond in Louisville got me to stop using tap water straight from the hose
Back in 2019 I was topping off my little 150 gallon pond every Saturday with water right out of the hose, and my goldfish kept looking sluggish. Then my neighbor Carl in Louisville showed me his koi setup and told me he lets a bucket of tap water sit out for 2 days first to let the chlorine fade. I tried it on my next water change and within a week the fish were swimming way more. Now I keep two 5 gallon buckets on the patio just for this. Does anyone else do the bucket thing, or am I overthinking it for a small pond?
