When did my water change I did it because I had a brown algae bloom. So I did a thorough cleaning so I only added in because I took all the established media out put new everything. So when I got API I used it for just that.So I've been watching this since this morning and I'm a little confused... So it sounds like It was an up and running tank. You did a large water change and didn't add "solution". What is this solution? chlorine remover? Also why add quick start? My basic understanding of it is that its a tank "jump start" chemical, which since your tank was seemingly established I'm confused to why?
