Hello! I am restarting both my tanks because I did it without proper research. A lot of my fish died after a month. I have given the rest back to the store. Some of the fish did die of ick. Anyway, I've emptied both tanks completely and re-filled them with clean tap water and cleaned the tanks while they were empty. I completely cleaned the filters as well so the tanks are like new. I currently have both of them running but I haven't got any dechlorinater or filter start. I will buy some on the weekend and add them to both tanks. I have aquarium salt but I don't know when or how to add that. I've heard that a little aquarium salt is good for a tropical fish tank. One tank is 170l and the other is 33l. The 33l has no decor, just gravel, a filter, a hood light and a heater. The 170l contains a filter, hood light, heater, sand (substrate), decor, a moss ball and an amazon sword (live plant). Can anyone tell me how to proceed further and how long to wait for the cycling because I want to do this right this time. Thanks!
