The last two mornings I have woke to find 1 or 2 shrimp dead, some with large wounds, one cut in half, below the current of the MP10. They are not directly below, but in the path of the current. I suspect that at night they find themselves swimming into the pump unknowingly where they soon get a serious beat down by the propeller. 6 shrimp in 3 days...no signs of illness or other possible causes. It has to be the pump.
Would it be bad to shut this down at night? Would plant health suffer from a reduced flow through the lights off period.
the other thing I'm worried about is shrimp or fish finding their way in when it isn't running and getting the same propeller karate chop when it starts up.
other suggestions?
I like using the pump, I see a good flow through the entire tank and would like to continue its use.
