Our Filter Media Cups are designed to fit sumps that use standard 4" filter socks. The Filter Media Cups do not fit inside Trigger System sumps using Single and Dual filter socks but will fit into the larger Trigger Systems sumps with a Triple filter sock holder.
If you are using a u shaped sock holder currently, you will also need the adapter ring to use your new kit, these are sold as an add on or as a set with the filter cups.
