I have spent many many nights just trying to catch those unwanted crabs and worms from my previous setup. So when I had the opportunity to start a new tank and these rocks came along, I just tot of giving it a try. At least I know these rocks are 'clean'. But that also means that these rocks are clean from the beneficial bacteria as well. The BB can be seeded I guess.
My first time experience with Aquaroche as well, so not too sure on the outcome yet. But it must be good!!! Haha
