I have a 37 gallon tank housing 3 small fancy goldfish. Iíd like to ditch the tank hood/light combo and let it be an open air tank and buy an external LED
light. I want to do this for aesthetic reasons, but also for the ease of tank maintenance.
Iíve done some experimenting with this lately, and the problem I keep encountering is that aquarium water smell that fills the room. That said, itís not awful, itís faint. I just have a sensitive sense of smell.
I keep the tank meticulously clean and do a few large water changes each week. Water testing doesnít show any levels of nitrates or nitrites.
Does anyone know of any tricks I could try to cut down on the aquarium water smell?
