NR-1 Pro All-In-One Media reactor (Bio-pellets, GFO, Carbon)

Our newly released NR-1 Pro nano media reactor packs all the latest and best features that our engineers have come up with. Building on the breakthrough of the original NR-1 high speed reactor design 3 years ago, we set forth to add all the features we can fit into the new NR-1 Pro. The NR-1 Pro allows ease of use and instant access to the media inside the reactor unit. Whether you want to change, add or mix, you can simply pull the top cover and it opens right up for full access. As usual, our NR-1 Pro like the previous unit is made with 100% extra heavy duty 3/16” thick seamless Cell-cast acrylic. The NR-1 Pro is specially designed to run with Bio-pellets of ALL shapes and sizes, GFO, Carbon etc. comes with 2 pieces of foam for GFO and other fine filter media. Another new feature is the use of a pre-filtering foam and strainer kit. This helps prolong the life and the efficiency of both pump and the media inside the reactor.

Anti-clumping design: utilizing a full distribution plate, our reactors give unmatched bio-pellet tumbling and flow distribution. Using a fully perforated specially patterned cell-cast acrylic plate, our reactors are high speed yet, gentle as the water comes up in a “curtain” style rather than a “jet” style stream. A “Jet” style stream causes excess agitation to the Bio-pellets and other medias hence decreases the medias efficiency.

Super small footprint at only 2.5" wide, this little reactor packs a good punch in effectively controlling and removing your Nitrates, Phosphates, slime algaes and other nuisance algaes. It can hold a strong dose of bio-pellets of up to 150ML giving you an aquarium capacity of 40G-50G (depending on your bio-load respectively). Yet it can still fit into an aquarium as small as our 8G, 18G, 34G Mini-II series systems.

Not as described

It's a reasonably well-made unit,with a decent pump, but definitely not as described on the MD website. Considerably larger than stated, will not fit in my nano sump. Had to hang on back with provided hardware. . No instructions included and the PDFs sheet on the web site is for a different product (maybe an earlier version??).

GFO? Forget about it

I got thi to put in my 29G biocube because it was one of the few on the market of this size that wasn't a hang on. The only problem is the pump is waaaaaay too strong and is like a cat 5 tornado for the GFO. The pump itself has a dial to control the amount of tumble but maybe mine was broken but it seriously starts off on hurricane and goes to aqua armageddon. Even with two filter pads stuffed into the chamber GFO shot out all over my tank in seconds. Maybe this power is good for bio pellets but its a joke when they say "...works great for GFO!"

Very satisfied!

I have been using this reactor on my 50 gallon sps tank for about one month and am very satisfied with my purchase. I got tired of my TLF reactor clogging and the pellets not tumbling. Due to the small footprint of this reactor, I fit the whole thing in my sump and it makes zero noise. The pellets tumble great with zero clogging. I have 150 ml of TLF NPX pellets in mine but I think you could fit more even though they say 150 max.
