I have a 30 gallon salt tank, and I dont really wanna spend 80 to 100$ on live rock. I will be going to the Gulf Coast of Florida in a week to go fishing. I have noticed when going through the channels out to the open water that there are barriers made of rock. There are also Islands made entirely of rock. I was wondering if this could be used as "Live Rock." Some of the rock is intertidal and some is submerged all the time. It tends to have some oysters on it too. I understand that it wont look as good as rock bought from the store but I am just looking for rock to filter the tank. Any help would be appreciated.
Thanks,
Billy
