Perforated Inserts

Our perforated ABS solvent weld (1.5") inserts when used with sponge blocks make an excellent final polishing stage. When larger flow rates are required they can be used in a manifold configuration (as below) using 1.5" solvent weld fittings. Sold separately.

Shown above is an alternative configuration for an under gravel filter


Shown above fitted with foam blocks	Four sizes of foam blocks are available

All blocks are 4" x 4" square with lengths of 6", 8", 10" & 12"

Sponge inserts as used in our Rotafold, Big Bertha and Power Fall Systems
