- PhosBan Reactor 550 - Two Little Fishies
The PhosBan 550 media reactor has a low profile and built-in hanging bracket making it ideal for "hang on the back" applications. The Phosban reactor can house your favorite filtration media.
- Great for HOB applications
- Includes ball valve
- Works great with Phosban Media
- Requires feed pump
The PhosBan Reactor 550 is designed to push water upwards from the bottom and through the media. This forces an even distribution of water throughout the media and prevents channeling from occurring. The PhosBan 150 can be mounted under the aquarium or hung on the back of the aquarium. It comes with barb hose fittings for 1/2" tubing and a 1/2" barbed ball valve included for flow control.
The Phosban 550 is compatible with any pump that uses 1/2" tubing and a flow rate between 100 and 250gph.
Max Media Capacity -750 grams
Inlet Tube - 1/2"
Outlet Tube - 1/2"
Max Flow Rate - 250 gph
Dimensions - 15.125" H x 4.5" W x 6.5" L
Distance required behind tank for HOB application - 5" min

HARD TO OPEN ONCE SEALED By Jeremy on 5/14/2019Jeremy would recommend this product to a friendThese reactors are great. The only downside is that they are a nightmare to try and open back up once they are sealed.
Even though I am the one to tighten it closed. I am barely able to reopen them. I think their is an issue with the orings but IDK.
I would still recommend them, Just don't over-tighten. Tighten them just enough to stop leaks.
Very low quality By Brian on 4/28/2019Brian wouldn't recommend this product to a friendThis reactor is made super cheap, doesn’t seal well and should sell for no more than $30 dollars.
leaks By chee on 11/25/2018chee wouldn't recommend this product to a friendincredibly hard to get this tightened so that it doesn't leak.
Not too shabby. By Tom on 5/21/2018Tom would recommend this product to a friendI bought this to use as a filter, so opening it consistently is not going to be a problem. The product works as expected. My only concern is the input and output are fixed in one location, so, it limits how you can place it in your sump.
Great Product By Chris on 1/4/2017Chris would recommend this product to a friendLove this for our 125 Gallon "simple" reef tank. I have it now in the refugium area of Triggers System sump and it works great! I have to clean it about once a month but even then it is not that clogged as some state. The elbows probably could use some better engineering, but other then that great product.
Buy something else By Medtoad on 11/27/2016Medtoad wouldn't recommend this product to a friendI have two of these that where put in when my tank was originally set up. The rubber connection gaskets are terrible and twice I've had them disconnect and pump water onto the floor (fortunately in a drained area) . Damaged many of my corals as my auto top off replaced the water and dropped my gravity to 1.018. The plastic pin spacer on the back also snaps off very easily. I've ordered a new reactor I hope will be better
Good product for a reasonable price! By acbear on 4/26/2016acbear would recommend this product to a friendI order this reactor to battle a algae outbreak. While the instructions were not real clear on how much GFO was needed to fill the canister to the min. two inch mark, I found it to work. It been a little over a month and my algae has died off to about half of what it was. I do have to empty the reactor twice to clean the sponge at the bottom but just reuse the GFO media after cleaning the sponge. Just change the media today since its been over a month and I had high Phosphate and Nitrate levels when I installed the reactor. Fish are swimming and more active now too. I only wished I had got this product before I set up my tank in the first place.
Bad Gaskets By Nate on 11/11/2014Nate wouldn't recommend this product to a friendI bought two of these before I realized how bad they are. The gasket is a thin rubber band that does not seat correctly when you screw the lid on. After a few media changes they leak. You get what you pay for.
Good for the price By Mike on 8/15/2013Mike would recommend this product to a friendThe fittings do worry me a bit in the very long term, but it is easy to set up and performs well. I use it for GFO and it can hold a lot and gets a good gentle, even distribution of flow through the media. Performs well for the price, and if you can mount it hanging inside a sump where it wont matter if it leaks then I'd say go for it for sure!
Cheap By Nikolai on 6/30/2013Nikolai wouldn't recommend this product to a friendReactor cheap clogged up very quickly internal rubber elbow made so short (cheap stuff) that it nearly enough sometime it slips the reactor made cheap it inconvinient jade sign is simply bad internal piping sometime disconnected and reactor won't working properly do not buy (waste of money)
quick and easy By Ryan on 12/22/2012Ryan would recommend this product to a friendII have two of these units. I use one for carbon and the other for biopellts. These units are really easy and quick to setup and they operate very well. They don't operate perfectly out of the box for biopellets, but for the savings a little modification was worth it for me.
What is the purpose of a reactor
GFO has a tendency to clump and harden into a rock unless it is agitated. A GFO reactor like the phosban (or other GFO reactors like ours, octopus, vertex, etc) are fluidized bed reactors. The water travels up through the bottom of the reactor and upwards through the media, which causes it to tumble lightly and prevents it from clumping.
Would you recommend using this reactor for biopellets?
Great question. This is not optimal for bio-pellets as it is not designed for the best tumbling of bio-pellets and there may be some clogs. Ideally selecting a bio-pellet designed reactor with the correct chamber to spin and tumble the media. Feel free to let us know if you have any further questions!
what are the dimentions of this reactor? and the 150 model please? Thank you!!!
The PhosBan Reactor 550 is 15 1/8 inches tall and 4 1/4 inches in diameter.
I hope this helps!
Have a great day :)
