My setup can be seen at

My question is this. I have a Beckett 1600 running most of the day for
the big waterfall effect, and a beckett Biofilter with a 350 gph running
24/7 through the fall as well When the big pump goes off at night, Isee
more activity in the big Koi. He seems to stay down low during the day
(400 gallons at 24" deep). He seems very healthy, and is an active
feeder, just seems to hang around more during the day than at night.

So, is my waterfall noise a problem? It is a lot of GPH but the effect
is nice. I might be willing to slow it down with a valve of some sort,
but currently like my results. Then again maybe he is just playing in
thecurrent created by that pump...

Any thoughts?

Thanks in advance

Carl
