I have a 20 high and I want to make it a 20 long. It will be dirted. I have an amazon sword and some bacopa that has hair algae on them. I’m also ordering a ton of plants and I want to bleach dip or do something to all of the plants I order and I already have to kill algae and pests. How do I do a bleach dip? Is a bleach dip what I need to do?
