Aquarium Advice Activist
Is lava rock an acceptable bio media to place in an aquaclear 110 filter? Would be placing one, or possibly two of these on a 46G tank for discus. Would Ammonia remover media or phosphate remover media help at all? Which sponge medica would be better, the white type from aquaclear or the black, egg crate style foam from fluval.. cut to fit into an aquaclear.
