It makes my house smell and I have no clue how to stop it... or make the smell minor. If you have any tips post please!
A fishtank should not smell really at all, never mind smelling up a whole house. What is your water change/cleaning regimen? I would start by doing some water changes, if the water is dirty enough to smell bad, the fish cannot be very comfortable in it.
I clean the water 1 time every two months as well as a gravel clean.
