I bought a USED 14 gal BioCube. I thought I was getting a deal but with all the cleaning, and now BRISTLEWORMS CREEPING OUT OF EVERY HOLE, I'M wondering if I should just get rid of all the live rock and cycle a whole new tank.
I heard that you can get rid of unwanted creatures by adding live rock into the water with very high salinity and it should make all of the animals vacate the water, so then you can pick out the ones you don't want and discard them. Although there might be some downside since this might kill a lot of other useful creatures.
