A couple of days ago I got my 55 gallon setup with Fluval Stratum and also got some "Natural Creek Stone" I got from Home Depot, thought it would be a money saver, look neat against the black background and substrate. I did rinse and clean the rocks. However, after 2 days have gone by I am noticing a sulfur smell. I've never used Fluval Stratum before but I also don't think that's where the smell is coming from. I have a feeling it is coming from the rocks. Someone had suggested I boil/bake the rocks but I do have a concern about explosions and not sure that would necessarily fix the problem--but then again I don't know. The tank is not stocked with any fish and won't be until likely after the holidays. Other concerns about the rocks, because hindsight is 20/20, is whether or not the rocks will alter the water chemistry, hardness, etc over time. I plan on doing a large school of neon tetras and possibly other fish that prefer similar water parameters. Haven't completely decided on everything. My gut instinct is to remove the rocks and find a new purpose for them, after all once plants are taking over the tank I probably won't see much of the bottom anyway. I don't know what type of rock these are other than they're natural creek stone and not cement. I guess the first question is to rule out the possibility that the Fluval Stratum would be the cause of the smell? Second is the likelihood of these rocks being an issue. I'm not opposed to removing the rocks but wouldn't mind not having to remove them either. edit: The water parameters after 24 hours after filling were: pH 6.6, GH 72 ppm, KG 36 ppm, Ammonia 1 ppm, Nitrite 0 ppm and Nitrate >0 but less than 5 ppm. I rechecked the water and nothing has changed (that I can measure).
