Hi guys just bought a 304b from flebay and im 99%sure it doesnt come with media. If it doesnt whats some cheap media i can throw in it. I do have 200gm of purigen that will go in but what cheap (to follow the cheap filter) should or can I use?
How cheap do you want to go? Lava rock is a pretty poor bio media but if you have a planted tank you don't need much. If you want better bio media than lava rock for cheaper look for those sintered clay balls used for hydroponic planters.
