Hi im sorry to say that the tank is very very milky and needs to be sorted out before you put any fish in it
if it was my tank first i would get the new filter up and running for a few weeks to build up the bio on the sponge in the new filter then i would stripe the tank down (which is not such a big ordeal as the tank is fairly small ) take out the blue gravel and replace it with something more natural then put some kind of background on the tank
if you are not aready using tapwater conditioner then buy a bottle and at the same time get yourself a bottle of nutrafin cycle
i know you have said that is the cam that makes the tank look milky but take my word for it their is some thing wrong with the water in that tank it may be that the tank is in direct sunlight but some thing is wrong
