This media reactor kit is a great first project for first time builders and an easy-to-assemble upgrade for anyone with acrylic crafting experience.

The kit includes all the parts need to build the reactor pictured. CNC machined parts fit together with ease and a detailed assembly manual is provided. This project can be put together in about an hour's time. The end result is a heavy duty media reactor that will last a lifetime and best of all, it works fantastically. Please take a minute to look through the PDF instruction manual below, there a lot more information on the reactor itself and you will get a good idea of what is involved with building an AVAST kit.

The kit comes standard with glue and everything else needed to easily install the reactor, including tubing, Antelco greenback valve, and threaded barbed elbows with a quick-disconnect union on the pump-input side.  Also included are mesh disks for easy, low-maintenance biopellet fluidization.  See the pre-built media reactors for more details.

Awesome kit with quality parts

Kit came well packaged with all the parts required. This was a nice evening project to work on. YouTube video was of an older model and could use some updating but otherwise straightforward. Looking forward to another future purchase.

Does the job

DIY kit went together perfectly. Only thing is that the down pipe is short and does not rest on the bottom plate. It’s cumbersome to put 3lbs of media in the reactor when the downpipe is connected to the lid. The space is limited as you fill it up. The reactor does work and fluidizes 46oz of chemi-pure just fine!

Fluidized Media Reactor Kits

I love Avast Marine Works products, I have purchased three reactors and they all ship fast, build very easily, and work well. I will purchase from Avast again in the future. William

Fluidized Media Reactor Kit

This Kit was simple and easy to put together. One of the more simpler designs. Easy instal as well. I recommend getting 2 90 degree fittings though.

Avast MR 16 You Build Kit Rocks!

Just built my kit. VERY high quality parts at a FANTASTIC price. As long as you can glue these together one step at a time you can own any quality Avast You Build product for a fraction of the cost of any other companies comparable product.. I highly recommend these to any and all reefers.
