ever heard of resin rock

[upsetter]

Anyone have any experience with "resin rock"? My LFS has some in their lr tank, said their supplier now has them sitting out in the ocean next to their regular live rock. Nice shapes, covered in corraline --pretty "real" looking & made of some sort of resin. Isn't porous so not a great bacteria host--but my thoughts were if I had a sump filled with same amount of lr I normally use couldn't I grow my corals on the resin rock in the display & perhaps not have to deal with the devil algae bryopsis which I'm currently battling? Seems like it wouldn't be able to get a real foothold on this stuff since it isn't porous & the usual cleanup crew could handle any of the "usual" easier algaes to deal with. My lr is about 5 yrs old & I think has phosphates stored in them from my learning days, been contemplating getting new rock.... Anyway-- just wondering if anyone had any experience with this resin rock?

I have some made by coralife I think.
I bought it originally to set up QT tanks with.
I used them in my main tank once when I broke the whole
thing down due to flatworms. I have to say the rock did look natural.
It was all on one side of the tank and once covered with coral it was hard
to tell the difference. what was not good was my rock is hollow with big
holes in it for fish to swim in. when I pulled the rock out after two months
to replace it with live rock the amount of detritus trapped inside the rock
was alarming. IMO it was okay for the short time I used it but I would not
use it for long term. hth.
