20# RUBY SAND (50# FILTER SAND REPLACEMENT)
Ruby Sand, porous ceramic, is a sand replacement that has been used by the water filtration industry for many years. The primary reason for Ruby Sands rapid acceptance by the filtration industry is improved clarity (3 to 5 microns) of Ruby Sand versus sand.
ONLY USE 20LB OF RUBY SAND FOR EVERY 50LB OF #20 SILICA SAND RECOMMENDED BY THE MANUFACTURER IN YOUR SAND TANK!
Example: A 150lb sand tank only needs 60lbs of Ruby Sand- WHAT A SAVINGS!
The jury is still out it's just the beginning of the season. Seems to be working well. The best part is carrying 20lb bags apposed to 50lb bags
