So i came home tonight and notice a fish tank 2 house down from mine outside in the garbage. i went and check it out and theres was a 55-60g tank, stand, heater,lid , light, sump/overflow type filter built into the stand, and some other random stuff. "CRAZY" theres lots of salt like substance in the tank so im pretty sure it was a saltwater tank. im planing to clean it up and take some pics soo u guys can help me make use of this tank. i wanna make a saltwater tank since i already have 2 fresh but ive never have and have no idea how to set it up or work.. the filter will be the main problem since ive never used that type of filter before. any input will be great. thanks in advance for helping out.. thanks..
