Hi I'm Back and have a question on mixing oyster shells and playsand
I read the thread on play sand and was wondering if you could mix little oyster shells (feed shells) with the sand. My daugther found a site that gave full instructions on making your own reef rock with Redimix morter and oyster shells is this safe?
Thanks for everyones prayers and well wishes.
