Mold in sump pit

My sump pit is plastic, but there is a hole cut in the bottom of it, and then a layer of gravel, and the pump itself sits on a paver stone so as not to suck the gravel up. However, there is a couple of inches of water that remains after the pump runs due to the pump being elevated. In this couple of inches of water, a grayish blob of mold has grown over the gravel.

How can I get rid of this mold? Someone had suggested I pour a little bleach in, but I'm not sure if that's ok since the pump drains to the yard.

As a side question, why would someone have cut a hole in the bottom? Is it to let any ground water from below the pump in? Is this normal or should I try to seal it?

The little bit of bleach you'd use in there would be diluted by the time it reached the lawn.

if you don't put holes in the sump, it'll pop out of the hole,,, boats float, remember ?

get a stick & scoop that mess outta there ! bleach will kill the remaining spores but won't destroy or liquefy what's there
