Spyglass Reactors

$ 179.99

The newest reactor from Avast Marine!  We have worked for quite some time to develop the most comprehensive media reactor feature set.  Combining gentle and complete fluidization, recirculating or single pass configuration options, media versatility, exceptional energy efficiency, and easy and quick maintenance into a design that is simply beautiful to watch, we present the Spyglass fluidized cone reactors.



The elegant and silent waterfall design eliminates the need for piping and fittings, yielding a footprint that will fit nicely in the smallest areas of your sump.  The Spyglass is for internal use only and can be used with a variety of media.  From the lightest resin type media like Purigen, to small pelleted Rox 0.8 carbon and GFO all the way up to the heaviest All in One Biopellets, we include a variety of mesh screens to ensure you have everything required to use virtually all media on the market today.  Additionally, we include the parts you need to configure this reactor as a single pass or recirculating chamber.  Simply choose one of three reactor sizes and corresponding optional Sicce pump.  If you prefer to use an external feed from an overflow or tee from an existing pump, this is easily done with parts included with every Spyglass.



The steep cone on the bottom enables complete fluidization using the smallest and most energy efficient pumps on the market.  This translates to less heat in your sump and fewer kilowatt-hours on your monthly utility bill. 



The way the reactor is effortlessly serviced will be appreciated by everyone.  There are no thumbscrews, no tubing and not even a union.  The reactor simply lifts off the base and the media screen is held in place with a press fit o-ring inside the reactor.  No need to even unplug anything; you can lift the Spyglass chamber right off with the pump running! No significant amount of media is lost out the bottom due to our custom made weighted silicone ball and optional fine mesh that sits in the bottom of the cone.  This acts as a check valve of sorts and effectively retains media with minimal cleaning. Changing out media has never been so hassle free!  We've also created a special rinsing lid that makes a quick job of flushing out carbon or GFO before use.

SpyGlass Reactor (Small)

This is an outstanding product that works as advertised. I now own 3 of them, 1 for Bio Pellets, 1 for Carbon and one for GFO. I have all 3 running off a manifold from my return pump.

Amazing Customer Service

Excellent and over the top! I had a modification needed to fit Spyglass bio-unit into Innovative Marine 80 tank, they did so without question and it works and looks amazing since it is located in plain view in sump area adjacent to the rear glass plate of tank. Highly recommend!


Update to My last Review

Still Loving the Reactor!!! I feel the same way as my first Review. The update is I Purchased the Quiet One PRO 1200 (317 GPH) - Lifegard for $15 at BRS on sale. Fits and works the best for the money!!! (NO Mods) I decided to buy 2 (Extra for Backup) and still cheeper than the other guys pumps. Very Very quiet! I am using it for about a months now and it tumbles the NPX Bioplastics - Two Little Fishies at 1500ML perfectly. Don't go cheep, buy the best solution.
