Product notes: Use only 1 oz. concentrate for up to 400 gallons. Any initial haze clears with filtration. Guaranteed to equal or outperform Leisure Time Defender. Shelf life: indefinite.
I just started using the filter a few months ago. So far it keeps the water clear. The defender chemical seems to work well too as the spa appears to be scale free. I put one once per week.
So far, working well. Update to follow.
