I just got a 10 gallon tank and it came with an internal filter but it has been getting cloudier since. I was wondering if anybody could help me fix this

have you done a water change? are there any fish in it? if so how many? what kind?

Is it a new tank or used? Also, did you rinse out your filter media and/or substrate? There are several things that could be causing this problem.

I just put water in yesterday that was brand new, the gravel is from a prior tank but has been cleaned, it has been set up since yesterday, i have 5 fish (2 cory's, 2 skirt tetra, 1 platy), it is a new tank

Explains a lot. I would say give it some time, but not so sure....how well did you wash the gravel? Reason I ask, if you have cleaned it too well, fully stocking your tank like that is going to cause you a lot of problems and potential deaths. If you cleaned too well, the nitrogen cycle is back to day 1. If the gravel had just been transferred without heavy cleaning then you would probably see a little spike, but it would clear pretty fast.

Do you have a testing kit? Not counting strips?

Quite likely a bacteria bloom. Make sure to keep an eye on water quality parameters.

It is probably dust from a brand new filter bag, i made that mistake once, put a new filter bag in without rinsing it first, tank gets super cloudy.
