Default Cloudy Water Overnight! Help!! UPDATED 12/4


Just wanted to update on the problem.
I had to go out of town for the weekend and I was a nervous wreck the whole time thinking about my tank.

When I got home the water was black! Yes, black! When I drained it out the water looked dark purple/black. I have no idea what in the world could cause this but I drained the entire tank and thought that maybe my sand bed hadn't been rinsed enough. I scooped all the sand out and rinsed it about 15-20 times washing the rest of the black out of the bucket. I don't think this was the issue as I had been using the same sand and it didn't turn the water black before but I just wanted to make sure (also wanted to rescape anyways).

I also have replaced the filterpad with a carbon filterpad since the last post thinking that might help. Not sure if it did or not. The filterpad also has a black sludge on it.

When I refilled the aquarium I did not use neutral regulator but just used water conditioner to remove the chlorine. After filling, the tank was crystal clear and looked great. When I woke up this morning the water had clouded a little bit again but not nearly as bad as before.

Any idea why the water might have turned black?

Here's a little background info:

Tank is 13 Gallons
Has Manzanita wood that has been sandblasted, rinsed and buried in the sand so it stays down.

I did a 30% Water change yesterday and I use Seachem Neutral Regulator to get the pH to 7 and eliminate the chlorine from the tap water.

I run an aqueon quietflow 10 without a carbon filter. I know I should probably have one but I am just using a filterpad for now.

The tank is only about 3 weeks old.

Anyways, I woke up this morning and the tank was super cloudy. It looks like dust being blown around in my tank.

My parameters are as follows:
Temp: 78F
Ammonia: 0ppm
Nitrite: 0ppm
Nitrate: 0 ppm
kH: 80ppm
GH: 120ppm

I use API 5 in 1 test strips to test my tank until I can afford an API test kit.

Does anyone have any idea as to what could be making my water cloudy like that? Calcium or something precipitating out of my water?
