I just purchased a used 75 gallon aquarium, and I have filled the bottom with plant soil and sand purchased at my local fish store. I have added nothing to the aquarium but water and substrate as well as stripping the caulk and adding a fresh seal. When I was cleaning my glass aquarium, I used a glass cleaner which is not intended for ingestion to clean the green residue off of my glass. It worked really well, but I didn't think about cleaning it up immediately afterwards. today, forgetting about the glass cleaner that was still on the glass from when I had applied it there to be cleaned, I filled the new aquarium with my substrate and then over the day about 70% full of water. I didn't remember the glass cleaner until this point. Right away I started draining my aquarium so that it is close to empty of water again. My question is, what do I have to do in order to clean my glass of the chemical which was applied to clean it. Am I able to keep my substrate? It was quite expensive and intended for a fresh new fish tank, if I can still clean it somehow and readd it that would be fantastic. I'm not sure how much effort is necessary to get rid of the chemical but I'm willing to do what it takes, Thank you
