can i use tuffa rock as live rock?
i have brought a second hand tank with lots of tuffa rock. the tank has been out of use for about 5 weeks now so all of the life on the rock is now dead.
can i use some of this rock to suppliment the live rock which i am going to purchase? will the tuffa rock be the same as the live rock over time? ie nitrifying and de-nitrifying?
i was planning on using a live rock filter in the sump, could i use tuffa rock instead? will it be efficent once the rock as become live?
