Ya know guys, it is legal to harvest "dead wood" from Forest Service Land in CA (also AZ too). Some areas have posted in their regulations that you have to buy a wood collecting permit but just give the office a ring and tell them you only need a few pieces for your fish tank, they'll most likely laugh and waive the fee. Oh yeah, the Forest Service and USGS websites typically have maps of manzanita areas because its considered a pest to the extent that they have to go clean it out every decade or so. It'll choke out the rest of the shrubs and small trees.
If you collect dead wood from the ground, in most cases you don't need to bake it at all. I have a few really long branches (5 ft +) that I just hosed and scrubbed the dirt off of and then soaked in a horse trough till it sunk. I've never had the white algae junk either, though my buddy who did use a live branch does have it on his more than a year later.
