Anyone ever use pagoda stone for a Malawi tank? Any pics? I have about 80lbs of pagoda sitting around unused, but I have been trying to find TX Holey Rock for the Malawi tank I am setting up. I would like to hear from anyone who has had pagodas with Malawis or at least seen it. I can't decide if I really want to pay for TX HoleyRock while I have all this pagoda at hand. Personal preferences? Advice? PICS?
