I was reading on the vivaria site about how they do some things, mounting wood included. They drill into the wood and then use basically kebab skewers pushed through the wood into the cocos panels to hold them. I just can't believe that the skewers don't rot and let the wood drop after a few months. I am kicking around the idea of taking a 90 gallon aquarium and making a vertical tank out of it. If I would do that, I doubt I could/would find a piece of driftwood I like that would be tall enough for the tank. I was thinking of mounting wood, and came upon that. I know I could use a few gallons of spray foam, but I really don't want to use it. I really like the cocos panels and definitely plan on using them. Any thoughts would be appreciated.
