Biofilter sludge?

[Emperornibble]

I have a 55 gal palu with a sizable area in rear which contains my mechanical/chemical filter, heater and my waterfall pump. I adjusted the temp and as I tried to put it back in its bracket, I stirred up the bottom of this side of the tank and my waterfall pump put it all in the front, planted side. Now the water is super murky. Is this bad for the fish I have in the planted side?

I'm going to do a water change, just have to let it settle first.

not a problem for the fish, but I would "dust" off the plants after it's all settled.
