Im starting my reef off with “dead rock” rock that was once “live rock” that has been used in someones tank or come from the sea and has been dried out. Dead rock is cheaper but takes more time to cycle in the first months of the tanks life. In time this dead rock will become live again.
Live rock is porous seas bed rock that is full of good bacteria that acts as a natural biological filter keeping all the waste products of the fish at bay, Mainly Ammonia, Nitrites and Nitrates. Live rock can prices vary from £10-£15 per kilo and im looking to use 10-15kg.
I managed to pick up 12kg of dead rock from eBay for £30 Bargain!
