Yup, I scrub the rocks before boiling or soaking and then let them dry on a towel for a few days. The only problem is when I run into a rock that seems to consist entirely of sediment. I scrub and scrub, but the layers keep coming and coming, and it feels grainy all over. I huck those ones back in the creek :) Holly -----Original Message----- From: gsas-member-bounces@thekrib.com [mailto:gsas-member-bounces@thekrib.com] On Behalf Of welenofsky@comcast.net Sent: Thursday, January 12, 2006 3:03 PM To: Greater Seattle Aquarium Society member chat Subject: RE: [GSAS-Member] Albino Bristlenoses Update They sell a lot of slate-type rock at Home Depot. I've used many different kinds of rocks in my aquarium with no problem. I just scrub them off good and let them air dry.
