I started a freshwater tank the other day but it had already been set up for like 2 months with an oscar in it. I loved my fish but he got to big and i wanted him comftorble so I gave hin to the lfs and got some mollies for my tank. I did a complete water change and a good gravle vacume but I want to know is my tank suppoed to smell like poop. It is rotten and smells like eggs man. I am wondering if I should over vacume it. I know I have plenty of filtration and I have two air stones and three plants but why does my tank stink. Can anyone tell me how to make my tank smell better please help.
:sad I want my fish to be happy and smell free
