I've always used them in other tanks. I prefer bare bottom for sure. In the future if I do a larger sps tank, it will definitely be bb. I still need to buy pods to add to the tank. Should do that this weekend. I have to drive an hr minimum for a decent store that sells snails and pods etc. So I get lazy sometimes and I try to get as much as possible with each trip.
I should specify, an hr minimum 1 way.
