Was about to through the towel in on my 250 gallon over crowded, over fed, over taken with hair algae and under maintained reef. I knew this was a long shot, heard about the pellets from a friend in the hobby. Now all I see is purple Coraline, this device kept me in the hobby and makes it enjoyable.

The top of the lid leaks where the bracket is held on to the lid. The elbow may or may not leak. I think it could be running down from the top where the screw for the bracket is.

its a nice little biopellet reactor and definitely worth the money however the pump that it came with didnt seem to do its job properly. tried multiple different things to get it to tumble the pellets and no matter what i did i just couldn't get them to tumble. the pump is a great pump, just a little under powered for the application. all in all though i would recommend this product.

As I already had extra half inch valves plumbed in on my return line install was easy except for tubing a little ridged for its length but nothing a little hot water or a hair drier can't handle. Fast shipment also ordered Wednesday got here Friday. Thanks guys!!!!

Love all things BRS but this reactor is not BRS quality in my opinion. Even for smaller systems, the biopellets quickly clog the screens even using a Sicce pump. I can't imagine how bad it would be with an undersized pump. Save your money and buy something else... the maintenance on this reactor will drive you crazy. Otherwise plan on cleaning the screens at least once per week.

This is everything you need(except a pump) to start running bio pellets. Great for smaller tanks. For all the bio pellets to tumble right it says to only use 350ml which is not enough media for larger tanks.

Easy set up . But I used a tee off of my feed line to my gfo and carbon reactor which is a tee off of main return to tank so no powerheads to burn out and no extre pump to buy. I just got it for xmas so dont know about biopellets yet.

Perfect for beginner... Highly recommended.

Love this combo try it with the maxjet 1200 but not enough after a while just upgrade the pump and in 5 days my nitrates were wiped out awsome

The kit is complete setup, only complaint for me is the supplied tubingis too short for where iIwwanted to put the reactor which is on the wall behind the tank right beside my BRS carbon and gfo reactors so Ihad to get longer tubing to connect. I also purchased a mag 3 pump to power it which Charlie at BRS ssuggested, I have 100 gal water volume so all the two cups of pellets supplied in the kit were used. There is a issue with getting all the pellets to tumble as needed even with the mag 3, the problem that I had is if I give the reactor full flow approximately 1/2 of the pellets goes to the top and don't tumble and the bottom half tumbles very good. I found "most" of the pellets tumble slowly if I throttle back the mag 3. I have not tried any adjustments to it as it has been running 5 days, I may try to teak it some more after running for a couple of weeks. Some others have complained of debris clogging the reactor, I hope this won't be an issue for me since I am using the foam prefilter supplied with the mag 3. They recommend once the reactor is running not to touch it for 6months and then only to add pellets as needed which is what I plan to do with only exception is to clean the mag 3 prefilter as needed, we'll see how it goes

Got this bad day in and it was stellar..... tried others first but now I realized I wasted my money.... so glad I have this now....

I got the Biopellet reactor with Mag drive 3 pump. It was fairly easy to set up though be warned if you attach it in correctly the push fittings are a pain to get unattached. The pellets tumble well but it seems a little temperamental and they occasionally get stuck up at the top. I have fairly low nitrates to begin with as its a young tank with only two very small fish but I like corals that eat and plan on having more fish so I wanted to get the biofilter started. Pros: very good quality for price straight forward set up good customer support seems to mostly work as described cons: make sure you double check where to attach everything as push fittings are a pain can be temperamental if debris ends up on the top of the media canister filter. The Mag drive 3 is supposed to limit this problem but mine has gotten clogged already. Overall i would recommend it to a friend who was looking for a no frills reactor for a great price. I am pleased to have an inexpensive option which leaves more money for corals

Love the reactor, I've stopped the vodka dosing and that freed up a dosing pump for my Mg. I'm using a Maxijet 12 (the Cobalt version) and it's tumbling the media just fine. I recommend cleaning the pump monthly. I slipped on that maintenance and noticed today the pump was not working. Not sure how long it sat but when I removed the reactor and pump to clean, SWEET JEEBUZ the smell was evil. Flushing with RODI and cleaning the pump with vinegar did the trick. Tonight's adventure has resulted in a new phrase around my house, "Alright, who's Carbon dosing?" LOL

I have 1 of these reactors and 2 of the black brs ones. They are perfect for GFO and Carbon, however i dont think they are ideal for Biopellets what so ever. After just 1 week the biopellets are barely tumbling because of gunk buildup inside the filter that restricts flow. This has to be cleaned weekly to keep the biopellets tumbling. Having to do this makes it a chore so I am seriously considering a different reactor. I hope BRS will re-design this reactor so that it doesnt clog as easily. Do not recomment for BIO Pellets. Only for GFO and Carbon.

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.

Easy to see ,Easy to adjust, Easy to add.

Product did just what the video said it would do. I found it very easy to use and setup. This is a very cheap way to remove phosphates from your tank.

I just got the system tuned in. I have my reactor about 14 inches over the top of the maxi jet 1200. And 12 inches above the water line. I put the whole pouch in the reactor to start and turned it on and it all clumped at the top. Tried screwing with the flow, and then took out about >1/4cup of pellets and not works great. Have it turned down to about 60% flow for the mj1200. Works great now. It's better that they gave me slightly too much then slightly too less.

This product is easy to set up and much easier to use than manual carbon dosing. I was dosing Ascorbic Acid twice day until I installed the BRS Bio Reactor. Now no worries about forgetting to dose in the morning or getting home on time to dose in the evening. Thanks, BRS

So I bought the kit and I'm very please with it. Some people have complained about the pellets clumping, but I have not experence this problem. Well built reactor.

This seemed like the least expensive way to try bio pellets. I am using this on a fish only system where I would really like to do fewer water changes. Between my vertex alpha skimmer, these bio pellets and GFO my nutrients and algae are undetectable. Not many reasons to do water changes now. I think if I still had a reef tank I would continue the water changes regardless.
