Hi! this was a good change... I have a question: how do you took out the old gravel? I want to take out my old gravel but i don't know a way to take it out without make a really good mess...
I kept all the fish in the tank and took out all the decor. Then I just scooped out all the gravel with a cup. I had the sand rinsed before I started the process, so it was ready to put in when I got all the gravel out. It is a pretty simple process, but it is a little messy. I managed to get a lot of water on the floor and all the agitation of the gravel made a lot of debris get kicked up in the tank. After I had all the sand in, I did a 50 percent water change.
