Cool beans man. What type of oak are they? I want to get some Live Oaks, but I guess they don't live that well up here as compared to Louisiana. Do all Oak tree leaves lower the pH, or are safe as compared to some other type of tree? Or do Oak leaves just decompose slower than other tree leaves? We've got TONS of acorns around here, so I'm assuming have lots of Oaks as a result...haha.
Do you just pluck them from the tree? or collecting them from the ground after they fell? What will happen if you add them when they are still green?
I'm tempted to give this a try in the 300gal. The water is soft, but the pH is in the lower 8's. Perhaps that what I need to do to drop it.
