Hello guys! I’m finally at my wits end about the situation of my axolotl’s tank and I’m hoping someone here can give me a solution. I’ve had my axolotl for around two months now. At some point my tank started getting cloudy and smelly (smell like sulphur, rotten eggs) and after searching online I concluded that a lot of debris had accumulated in my sand substrate and anaerobic bacteria started to form( parts of the sand had started turning black too) even though I would weekly vacuum it. Also along the cloudiness and smell some sort of disgusting yewllow-y slime would form on the plants, surfaces and even when I cleaned the filter media everything was full of the stuff and everything, and I mean everything in the tank, even the moss balls, reeked like rotten eggs. At some point I removed the sand (but I didn’t rinse anything else so as not to kill good bacteria) and did a massive almost 95% water change. After that I hoped that the problem would be solved but slowly after 5-6 days the cloudiness came slowly back and so did the smell but not as strong. I did my last water change 5 days ago. The tank is cloudy as ever(though surprisingly not as smelly, almost no smell) and I honestly don’t know what to do. This has honestly taken all the fun out of keeping my little friend and I just can’t bear to look at the tank like that anymore. My parameters have always been good during this time, no ammonia, no nitrites, nitrates low, so it couldn’t have been a parameter problem. I even put shrimp inside the tank and those that didn’t become snacks still survive and I know how sensitive shrimp can be. Water temperature is always between 15-19 degrees celcius so I really don’t know what the problem is! Here are some photos of my tank(sorry for any reflections) Thank you for any advice you may have!
