Pentair Aquatics Modular Filter System

[Nuts4fish]

Has anyone had any experience or knowledge using the Lifegard Modular Filtration System?

Here is a link http/www.pentairaquatics.com/2005/2005_detail/AFK.htm.

I have been reading through old posts and don't see too much discussion. I have an opportunity to pick this up at a great deal.

Thanks
