Terrible Advice Tuesdays (T.A.Tues): Saltwater aquariums smell bad.
The rest of the story: A healthy saltwater tank that has good water quality and good filtration will not smell.
If your saltwater tank does smells bad, the first place to look is water quality. A tank with poor water quality (high ammonia or nitrates) will likely smell bad. And a tank with poor water quality probably has something wrong with it such as a poor biological filtration, lack of chemical filtration (namely activated carbon), little/no surface skimming, or a dead fish in the tank.
Even a protein skimmer cup that is full of nasty skimmate should not be noticeable when you are standing in front of the tank.
If your saltwater tank smells bad, that’s not normal and a prime indicator that something is wrong.Browse the Store! Questions?
