TANK UPDATE: So the fog on the sand didn't go away and I talked with a friend of mine who is an aquarist and she said it might be bacteria that could hurt my fish. So because I don't have any fish in there yet and I don't have my filter or heater or testing kit yet (all these things are supposed to come today so I'm super excited!) I did a 90% water change and then treated the water with conditioner, the second picture is after I did the water change and treated it. I thought it'd be fine to leave untreated water in there but I realized that might cause bad bacteria growth that would be a bitch to get out so. If I get everything today then I'll do another tank update tonight, I'm currently studying for a math test and trying not to cry so. 😭 Thanks @aquariumsinadorm for the help!!
