the reason i asked is because someone is selling a tank with a stand, but it comes with two sumps and if i did decide to buy it maybe i could just use the sump for filteration instead of going and purchasing another filter? i quickly looked at the set up this morning and i saw a sump under the tank filled with a bunch of blue bio balls, but i dont know if it comes with a pump. i dont know too much about sumps so im trying to do some research on how to use on and hook one up.
