I did about a month of solid research before committing to bio pellets as a form of biological filtration. After scouring the web, I decided to give the bio pellet kit a try.

The reactor was super simple to set up (total set up time was around 15 minutes). The reactor is made from heavy duty plastic. Another quality product from BRS!

After 8 weeks, my Elos nitrate test kit tested between 2.5 - 1.0ppm nitrate (the colors were too hard to distinguish). My nitrates were stuck at 10-15 ppm for the past year no matter what I tried (water changes, chaetomorpha). Simply unbelievable. My nitrates are dropping by the day.

Make sure you read, and re-read the instructions on the BRS website---it'll save you a ton of time and headaches down the line.

Like the instructions say --- be patient! I tested nitrates almost every other day (I'm impatient like most reefers), but the patience finally paid off after 8 weeks.

You'll need to have a decent skimmer if you run bio pellets, otherwise you won't see the results (or so I've read). My Tunze 9002 skimmer started to produce dark tea-colored skimmate after running bio pellets.

One tip though---do NOT purchase the Maxijet1200 pump if you plan on running a smaller pump with this reactor. The newer Maxijet pumps rattle cos it can't handle the head pressure. Instead, order the Cobolt Aquatics pump (made in Italy). I'd recommend going the Mag3 if you can (like BRS recommends).

Like some, I experienced cloudy water, but as long as you have a decent skimmer, and lots of water movement, you should be fine. My livestock and corals survived, and are now showing full polyp extension. If you have an ORP meter, keep on eye on it so that your oxygen levels don't drop too much. Install extra powerheads if you need to oxygenate your water. The cloudiness subsides after 3-4 days. However, your results may vary.

Above all, be patient, follow the instructions, and you shall be rewarded. I'll definitely run my next tank using biopellets.

I got the combo kit from BRS just recently, so I can't comment on the effectiveness of biopellets in my system yet, but this reactor is the same quality build as the dual GFO/carbon reactor from BRS I run on my tank and love it. The included canister is key in maximizing up flow in the system. I had this thing hooked up in minutes, and got a perfect tumble thanks to the included control valve. In my experiences with BRS products, if you want to get great product at a great price, it doesn't get any better than this! Highly recommended.

Great product for a great price. Looked around a lot and was unable to find anything similar for even close to this price AND the biopellets are included! low nitrates with happy fish and coral! Would buy again.

I have 2 of these on separate tanks. They are easy to use, a great price and easy to set up. No complaints here. Another great but from brs.

I've looked at more expensive models but BRS reactors work great. Great quality and great service.

Great value... this is priced less than other reactors on the market and works great!

this system workes great i think its a mush have for the tank

A complete kit for biopellets - just add water...and a pump. Pellets need good agitation within the reactor chamber so dont skimp on the pump output.

Its everything you need to get the reactor going, and if you get at all confused with the set up, they have a movie outlining everything you have to do

I'vs been dosing vodka per the reef central write up for a month now, with inconsistant results. As a scientifically minded person, I wanted to try. Vodka dosing for the experience but found that my nitrate levels were variable, not to mention the cloudy water. I put the brs biopellet reactor in a little more than a week ago, and gave one last dose of vodka. My tank cleared up in a couple of days, then a small bacterial bloom with cloudiness, now my skimmer is pulling out dark stinky stuff, my water is clearing up, and my nitrates which have been at 40 since the day I put uncured live rock in my tank 4 months ago have come down to 20 in a few days. Will update when they hit 5. Water is crystal clear now, and fish are happy. Pellets tumble good with the mj1200 but i wish I had bought the double reactor , mag drive 3 and the biopellet canister so i could run a carbon reactor before the biopellets off the same pump.

i ordered this kit for my 55gal it work well, 1 week after added with zeobak tank lookin good sps color is brighter. but skimmer is acting up, wish the push connector was a bit better it leak a bit at first

Ive had a noticable decrease in Nitrates, and my corals are doing great. Ive been using it for 5 months and very happy with the results. Only downside is I have to clean it every week because the strainer gets clogged and pellets quit tumbeling.
