Aquarium Advice FINatic
IM planning on rescaping my 20g high this spring break and i want to have the sand taller on the left side of the tank. However from what i have read, u have to aggitate the sand to prevent dead pockets but i don't want to mess with my plant's roots. Do i have to aggitate the sand? What is so bad about having anaerobic pockets in the sand?
