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

This reactor is awesome it’s very easy to fill and adjust flow cone design keeps media fluidized preventing clumping and since these use Sicce pumps they are dead silent, I was using a Nyos reactor prior and it didn’t tumble the media as good as the Spyglass does. Also seen comments about screen not bring able to be leveled this wasn’t an issue for me I used the supplied silicone grease and was able to install the screen as designed. I would recommend this to anyone that has room in their sump if no room take a look at the external media reactors.

Best GFO reactor I have ever used.

The spyglass reactor is the best and most efficient design for a GFO reactor I have ever used. I have tried several. I like the cone approach to keeping the gfo from clumping and sliding up the column of the reactor. Nice product, easy to change media. Sicce pumps are excellent as always.

Spyglass unique reactor

I struggled finding the right Sicce size pump because it has to fit the chamber as the flow needed to be on center. I ended up buying a bigger size pump for more media and place it outside. The reactor is one of its kind and I like that you can change the media easily. The screen however does not level so easily.
