Dr. Drydens Activate Glass Media - Grade 2 - Coarse

Easy to install and seems to work great. Time will tell as I have only run for 8 hrs as of this writing but I did notice that in my Sand Dollar SD60 that the starting pressure is reading 11 psi where with clean sand it is around 15 psi.

Quick shipping and exactly what I ordered. Easy ordering and great experience. Will be ordering from here in the future!

My order came fast and in great shape. I always appreciate the fast service and the accurate delivery of my items.
