PM Jetskisteve, he should be able to get you some good live rock, of course, shipping is a bit painful. When I got some off him it came out to about $15/kilo shipped, Which is only a few dollars more than just dead baserock from the lower hutt pet center. They're the cheapest place locally for base rock at $11/kilo. For a 100L you'd want somewhere around 10-15 kilos.
Oh...Just noticed you said to talk to Pies, Steve. hehe. You tell him how much you charge.
