Same here...I use Fritz.I've been mixing up 50 Gallons at a time in my garage where it often gets over 100 degrees. It usually takes me 7-8 weeks to use up the entire container. I test parameters after every water change and they're always right where they need to be. So I've noticed zero ill effects from this.
