I see so many people on here that have some amazing pieces of driftwood! Where do you find them? I live in Florida around the Clearwater area. Many of the areas that might have driftwood are brackish waters and I have freshwater. A little afraid to just grab something out of those waters for my tank but I really, really want a good centerpiece for my 75 gallon. I don't want to spend a ton of money on something from a company cause frankly they cost to much and all they did is pull it from a stream anyway. Any suggestions?
