With my recent larger build the sump compartment has a stronger odor mainly coming from the larger skimmer. Although the smell doesn't affect the room much you can smell it when I have the doors to the stand open. Also as the skimmer cup start to fill the odor will sometime escape into the living room. Was curious if anyone uses a reef safe odor Eliminator For in the sump area? I do run carbon but this is primarily coming from the skimmer air. My gf has these odor eliminator beads that have fragrances she uses in closest in our place not sure if they are reef safe, baking soda?

)anywhere in your tank. I don't know of any odor eliminator that I would feel safe using in the enclosed confines of the sump. Just have to empty your skimmer cup more often.
At least it sounds like your skimmer is well dialed in!
