scuzz in not yet cycled tank

[Oreganoodle]

I had planned to start up a new tank, and had gotten as far as filling it up and de-chlorinating - bringing it up to temp etc. The plan was to start cycling the next day (fishless cycle). And then the dog ran into me and dislocated my knee.  For about a month I've not even been able to get to the floor that the fishtank is on - so I just let it sit and unplugged the filter/heater.  There was no bacteria or anything besides de-chlorinating chemicals added.

Now that I am able to get back to the fishtank - there is a film/scuzz floating along the top of the water. It is off-whitish and gelatinous, but relatively thin. A bit like pudding skin.  My thought is that is just to turn on the filter and let it run for a day while the tank comes up to temp and then proceed.

Any reasons that might be a terrible idea?

It could be - it looks kind of like it.

I don't think it would do any harm then

I would be very leary. I would think Stagnant water grows bacteria you don’t want in the tank. I’m not an expert though so hopefully someone has experienced this and will chime in.

That could also be true. Sounds like it's just best for you to start over just precautionary.
