Chad Posted August 18, 2021 Share Posted August 18, 2021 I'm trying to track down a stressor/problem in my aquarium and I could use some insight regarding the smell of a tank. My tank smells earthy, like dirt, most of the time. I believe that's good, planted tank (20 gal long, floating, mosses and ferns), populated with 15 guppies, a bristle pleco, 15 shrimp and 4 mystery snails. But when I clean it, specifically gravel vac it, it smells like sulphur (rotten eggs). Is that an indicator of something bad? Seems like it would be. Are more water changes the answer? My levels are all good I think (amm 0%, nitrite 0%, nitrate 10%, ph 7.4, kh 5, gh 9) except for phosphate which comes out of the tap at 1.0 ppm and is currently 3-4 ppm in my tank. Don't know what I should be looking for but generally the fish have clamped fins except for a couple of them. I worry I overfeed them but it's not excessive, meaning there isn't food in the tank after five minutes, but I have dealt with swollen bladder issues in the past so I'm working on it and still trying to find the perfect amount. Any insights are hugely appreciated, thanks so much! Link to comment Share on other sites More sharing options...
