water was changed because we moved our betta to a bigger tank. we just use anti chlorine and nitrifying bacteria added a few plants and nothing else. parameters optimal but a few days after moving our betta this thing happens overnight (it was very clear the day before). betta is doing great very healthy. just never had this happen before. any advice would be helpful!
