i always do but they say not to,haven't lost a koi for 10 years

Answer 2

No and only clean any of it with POND WATER. Not tap water

Answer 3

nobbly bits at the bottom are where the aerobic bacteria live

....those help to control ammonia in live tanks

....also, use pond water to rinse the filter sponges, or dechlorinated tap water in a bucket....
