The good folks over at Precision marine launched their “Pro Series” line of substrate reactors. These reactors feature among other things: Cell-cast acrylic tubing throughout, 1/2â€ Thick, full-gauge machined Black PVC base, PVC Welded flanges, 3/4â€ thick, machined threaded Heavy-Duty Lid and Unique thermoformed base which is said to redirect the water up. That’s nice and dandy, but we’d be happy with a price and release date. You’ll be able to see these units atÂ professional fish stores and custom aquarium builders/installers no doubt. They are only releasing the substrate reactors as part of a “pro series”,Â so we are wondering what else they have in store with their “pro series”.
