I was wondering I have some rock that used to be live when it was in my tank. There was to much of it so I put it in a bucket. I was going to set up a sump and was wondering if I can put this rock in the filter. Also if I do put it in wet dry and take out the bio balls can the water trickle off some of the rock or does the rock need to be complety covered in water.
Thanks
