Tufa Rock

Wow tufa rock for a reef I don't recommend it.
I have used it about 15 years ago it was of to use,lots of algae problems and the possibility of leaching metal traces into your aquarium in my opinion yes you could use it but is it worth the problems that be released by the rock.
I would spend a little money for the safety of the inhabitant going into your tank.or better yet you will see some reefers every now and then shutting down their tanks and you might get lucky with a good price but you will never beat 0.30 cents a lb if you are taking the plunge.
