I am helping my daughter set up her first tank.
It is a 12 gallon tank.
We bought some flourite as we intend to add live plants.
So, I rinsed the flourite and it looked like we got it running clear.
However, after we put it into the tank, it totally clouded up with what was obviously what I had missed in the rinsing.

After a few hours of running my filter, the red stuff has substantially cleared but the water looks cloudy.

Should I just remove the water and re-wash the gravel?

Any advice would help.
