Hey guys I have a 20 gal, with a hood, 20 lbs of gravel, and a sponge filter ( all you need is the air pump) for $35 or best offer. I live in south florida, so of course if you can't pick up, shipping rates apply. If anyone is interested let me know. I upgraded to a bigger tank, that's the only reason I'm getting rid of this one. Need to downsize! Oh and It's a tad bit dusty, lol sorry, so I promise when someone buys it I will do a nice cleaning and hose it down for you! also my sponge filters are in the bag, They're really good quality, just need to be rinsed and squeezed. I'll only be giving one (its huge) with this tank.oh and the black stuff is sand ( it was my substrate in this tank) so don't fear!
