Power filter down overnight.

Hello,

I have two filters running 24/7.  One is an internal filter, the second is
a 
large canister filter.  Would it do any harm to the fish, water quality or

the filter itself, if I powered down the canister overnight?  I was
thinking 
about setting it on a timer to only run between 8am and 11pm.

I would continue to run the internal 24/7.

Gary.
