i am trying to replicate a mangrove lagoon aquascape and i need to come up with a way to make wood sticks reef safe as i have heard even driftwood will lower ph. i do not want to use any of the synthetic wood ornaments i have seen available on the market as they are all in the form of small tree trunks and i need several different large sticks (130 gallon aquarium). i also do not want to grow live mangrove. could i coat driftwood sticks in a dark brown stained epoxy resin. anyone have any ideas?
