Are you looking for clean rock?
I have some 2 year old rock, but it has Vermetid Snails.
Current PO4 is 0.02 and NO3 is zero. My tank has always been close to low nutrients, so you'll not have an issue with nutrients leaching.
The structure is made up of about 5 pieces of Real Reef Rock from J&L and can be broken down if so desired.
Abouth 1 month from now I'll be selling a 20w x 10d x 8 tall structure with some encrusted corals. It's a semi-circle with 2 swim-throughs.
It has some kind of Cali Tort, Teal Turaki, Setosa, Super Pink Milli, Tri-Color Nana, Red Lemonade, Purple Stylo, a Red Acan colony and whatever stays behind from my Gorg.
There are 2 years of encrusting corals here and some of them cover the spans between pieces of rock. There's a lot of encrustment happening.
So much so that the Setosa has started to plate up into nowhere !!!
I'll be cutting the larger pieces of what I want to keep.
The rest goes with it, including the whole colony of Cali Tort shown in the second pic.
It's the structure on the right, minus the rocks on the sandbed.
