The Phosban Reactor 150™ has become a staple amongst most aquarists who keep SPS corals. So much so that you often see Phosban used interchangeably with the term GFO or Granular Ferric Oxide. To meet the demand of larger tanks and reduce the number of Phosban Reactors needed, TLF has created the Phosban 550 reactor for aquariums up to 600 gallons. It can be mounted hanging on the back of the aquarium or below the aquarium. The pump used should have a flow rate of 100-200GPH. Includes ball valve for regulating flow, and flexible connection fittings that rotate 180 degrees to allow a perfect custom fit to your installation. The threaded lid design makes servicing quick and easy. One reactor for aquariums up to 600 gallons.
*for activated carbon or GFO/Phosban use ONLY.

i have been using 3 mesh bags full of Phosban for years with OK results...not exactly zero phosphates, but manageable. After one day of running the reactor, my phosphate level is at zero and I have been able to remove all 3 bags. Easy to install and operate. Excellent product!

I decided to try this out as a bio pellet reactor using the same technique they use in the video. I have a 100gph pump hooked up running about 250ml of pellets. The reactor seems good and sturdy. I gave it 3.5 starts because the bottom diffuser plate is crooked, I don't have any pellets sticking or anything but they could at least put the pieces together strait.

Use this reactor with Brightwell Katalyst and I think it works great and with a single pump 1800 l / h, I have the 550 but that requires a huge bomb, so I liked this.

Excellent Product. Struggled with Phos control always trying to get to zero without success. 48 hours later went from 1.0 to .25. Well worth the investment.

Worked good with the NPX BioPellets, except for the clumping issue. I had open up, stir the media to remove clumps, and hook it back up on a monthly basis. I started with a Maxi-Jet 1200, which is recommended by TLF, but it was not powerful enough to prevent clumps due to dead spots. I was cleaning the reactor to ready it for set up with a stronger pump, and noticed that the clear acrylic housing was severely cracked all over the entire clear sleeve of the reactor. Lasted a year:(

I actually hooked a maxijet 1200 because i had one and since this reactor comes with a control valve, it worked great! Easy to setup and can't beet the price!Does not leak like others have said! I am running phosguard through this reactor and tumbling it slowly no problems! I need two more reactors one for carbon and one for bio pellets. I will be purchasing two more! Great price

I like these little reactors and have 3 of them. However the screw on lid can be made better with some kind of prongs on the side as to be able to grip them better. They do tend to crack on the sides of the lid if over tightened. Should be built with a thicker plastic to handle more pressure since everything in this hobby seems to be a leak waiting to happen. Don't think I will be buying another one.

Since purchasing my two little fishies phosban reactor, my hair alge problem has stopped. Im fairly new to this hobbie and i am having fun with it. I was having problems with hair alge in my 30 gal tank. So i purchased my phosban reactor and havnt had a problem since, its great my coral seems to be doing great as well. The water quality is much better. keeping up with my water changes and things look great. Seemed to be learning more every week. Thank you

I decided to get one of these to perfect my water parameters to the desired levels of "perfect" I have mostly achieved that now after 2 months of use I can now feed my tank how ever I want to and see no harm done. I initially experienced the "leak" everyone who has something negative to say about these speaks of, and well after careful observation and investigation I discovered the lid was not getting screwed down as far as it could go. After putting more pressure on screwing down the lid, I have NOT had a single problem out of this reactor. I've been running it with the biopellets, and am now set to get a second reactor to run gfo in. If you are on the fence about getting one because someone said these leak, perhaps that person got a bad one? I've been enjoying mine. If those other folks were seeing leaks around the top, perhaps they just needed to put the lid on correctly as was the case with my experience? I hope my review is helpful. It's been a good product for me so far. I've been keeping and maintaining mixed reef/fish tanks for 23 years if that means anything.

I have two of these; one for my probiotic and the other recently installed for phosphate. My probiotic unit has been installed for nearly two years using bioballs from LFS. It has worked good but I have now needed to replace the rubber elbows as they have hardened and don't function as designed.
I would recommend this unit for the cost.
