I have a 20h with auratus to be in soon. I have a piece of wood from the pet store in the water and partially out. the part out started growin mold on it. little white dots every where. is it cuz i have a wrong type of wood? they said it should work. but also, i cant yet figure out how to keep the temps down. they're gettin to almost 90 during the day if its hot, and i know this is to high. so, first, how do i stop the mold, is it cuz of the temp? and also, any tricks on keepin temps down a few degrees? thanks
