Hi,
One of my friend bought some LR and place it into the tank 1 hours ago. However, the LR rocks really smell, and so does the water.
If the rocks are really already DEAD, it is advisable to scrub them & dry them under the SUN to get rid of the smell? Then later put use it again.
Worry that the rocks may pollute the water, and LS may be affected.
thanks in advance.
