Dr. Drydens Activate Glass Media - Grade 1 - Fine

The shipping was incredibly fast especially considering the order contained 450 pounds of material. And FREE! WOW!!! The water clarity has shown a noticeable improvement. I went to vacuum the other day and, for a second, thought "Where's the water!" It was so clear! However, I did not have a good experience with their customer support. I was inquiring about another product through the chat and phone but received no answer.

I love this! I would have had to change out sand filter balls 4 times already! With Dr. Drydens glass media, I only have to backwash and rinse for a few minutes a week and it keeps the water looking phenomenal!

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.
