Frequently Asked Questions
What is the benefit of a top-mount filter like the PPG Filter Top?
Top-mount filters position the multiport valve directly on top of the tank, significantly reducing the width required in your plant room compared to side-mount alternatives.
Can Blue Cube Direct install this filter for me?
Yes. We offer complete professional installation services. Call our technical line before ordering to confirm your plant room requirements and book an installation date.
What filter media can be loaded into the PPG Filter Top?
It supports standard silica sand and gravel combinations, or active glass media including AFM Grade 1, AFM Grade 2, and AFM Grade 3 based on the specific model capacity.
