Well, if you didn't do all those big water changes you'd be halfway to buying a recirculating reactor. The problem is that you need a fair bit of flow to keep the biopellets churning otherwise they clump up. Ime, you don't want that much flow going through the biopellets. See what you can find for a used reactor. The one I use is a Reef Dynamics biopellet reactor. I bought it used at a fraction of the cost - they are pricey.
