Melissa Ann Posted February 5, 2021 Share Posted February 5, 2021 This is my dirted 20 gallon long that I literally lost every fish in (ich outbreak). I am rebooting and need any and all advice on what to layer on top here before adding new fish. There was a sulphur/rotten egg smell in the tank that I noticed while emptying. Comments? I was planning on adding more sand (10 pound bag) on top before filling but am wondering if gravel first and then sand might be best. Advice? Can the phenomenal fish gurus here advise?
