I do weekly water changes too
I like my fish and add extra ferts for the plants. I guess I'm not running an El natural anymore.
mistergreen, I agree with you when it comes to a traditional aquarium. My El Natural is running perfectly without a filter and the currently fish load. But of course I want to add more fish
I just don't want to mess up a good thing. Maybe I should just leave this aquarium alone and start a new one. There is always space for one more tank
