Silica gel replacement

[Quinster]

I use it with my ozonizer and when you purchase it, the chips (I guess you could call them beads) are white and as they get waterlogged they turn a yellowish color. I too run it before the inlet of my ozonizer, my drying chamber is 4" x 10" and it changes in approximatly 1 1/2 - 2 months. A 5lb bag lasts about 6 months and cost me $4.99 (plus tax of course)
