I've been noticing a strong odor upon walking into my home, especially after I've been gone for a few days. It is not a pleasant odor and sometimes makes me a bit nauseous. I suspect it may be coming from my 60 gallon planted tank. It has a sand substrate which is about 2-1/2" to 3" deep and a few valisneria plants, which aren't doing so great despite my efforts. Most of the foliage looks healthy, but a few leaves are brown. I trim them periodically though, so I don't think the plants are the issue. Filtration is adequate (Aqueon Quietflow 300 canister). I'm wondering if gas could be building up beneath the substrate and releasing into the air. I can't think of what else it could be. I have six geophagus that constantly sift through the substrate, so perhaps they are constantly disturbing the gas? Should I remove an inch or so of the sand and maybe even mix in a more coarse substrate to see if that helps? I only used sand because I used to have Corydoras, but they are in another tank now. Plus my plants aren't doing so great, so I wouldn't mind changing out some of the substrate. I have both Aquasoil and eco complete on had.
Lastly, are there companies that test aquarium water there a way tofor harmful (to humans) bacteria?
