I’ve had my tank since about March and It’s always had white cloudy water problems. I had a betta in there (it wasn’t this bad when he was around) but he died a month ago sadly. Ever since (yes I removed the fish) the tank has been particularly bad, everyone online always says to wait it out or add beneficial bacteria but nothing has worked. I’ve even tried using seachem conditioner and API Accu Clear but nothing works. Please help me fix this so I can bring home another pet.
