I have a 300 gallon pond with a oversized filter and pump. (1800 gph)
While it keeps the water clear it also makes a lot of water movement. I
am going to waterfall it soon. I was told that shutting off the pump 1
hour twice a day would not kill the good bio bacteria. I need these 2
hours so I can feed my fish and turtles. I also was told by a petshop
that even 12 hours would not hurt the bio filter. What do you all think?
Thank you
