Perma-Beads ® are specifically designed sinking beads toreplace sand in any sand filter media system. There are no plumbing changesneeded. Perma-Beads ® eliminate clogging, compaction and channeling in anysize, make or model sand filter.
Advanced Aquaculture Systems offers free technical support to determinethe proper volume of Perma-Beads ® to replace sand in any sand filter.
SURFACEPROPERTIES The very hard surface properties of Perma-Beads® preventbacteria from etching into the surface and the very slippery surface allowseven the stickiest waste to be scrubbed off when the bed fluidizes uponbackwash. In fact, as Perma-Beads® age, they remove smaller particles as a thinfilm of nitrifying bacteria covers each bead. These are the same bacteria thatcreates bridging, clogging and channeling in other media, but in Perma-Beads®,this mechanism actually serves to trap smaller particles that are then easilyremoved in the backwash cycle. HOWTO CONVERT SAND TO PERMA-BEADS®
There are no plumbing changes required when converting a sandfilter to Perma-Beads®. Simply remove the sand and pour in the Perma-Beads®. Todetermine the amount of Perma-Beads® required, take the sand filtermanufacturer’s rating for pounds of sand, multiply by .6 and divide by 55.Round up or down to the closest whole number. This is the number of cubic feetyou need. Sold in 1cubic foot boxes, 12” x 12” x 12” (weight 55 lbs).
