We carry a wide variety of reverse osmosis canisters, and depending on your system or reactor we most likely have the canister to fit your needs. The most common RODI systems along with the BRS systems use the 10" Canister with 1/4" ports*. The standard and dual BRS Reactors use the same 10" canister but with 1/2" ports, and deluxe reactors use the 10" canister with 1/2" ports.
Sizes Available:
- 5" x 2.5" Reverse Osmosis Canister with 1/2” Ports (BRS mini reactor canister)
- 10" x 2.5" Reverse Osmosis Canister with 1/4" NPT Ports* (typical replacement RO canister)
- 10" x 2.5" Reverse Osmosis Canister with 1/2” NPT Ports (BRS carbon & GFO canister)
- 10" x 2.5" Reverse Osmosis Deluxe Canister with 1/2” Push Connect Ports (BRS deluxe carbon & GFO canister)
- 20“ x 2.5" Reverse Osmosis Canister with 3/8” NPT Ports
- 20" x 2.5" Reverse Osmosis Canister with 1" Ports
Note: Fittings are not included. Canisters with pressure relief ports may have a red or green button and may vary from canister to canister.
*Regarding 10" x 2.5" Reverse Osmosis Canister 1/4" Ports (SKU: 200001): Manufacturer changes to this product now cause the ports to not properly line up with the older style canister. If you are replacing a canister on an older BRS RO/DI system, you will want to replace all canisters that are linked together with nipple fittings. Alternatively, you can use 1/16" Nylon washers on the new style canister to get them to line up.

Will the 20 inch canister with 3/4 ports be clear? Also if I use for di resin how much will it hold with appropriate canister installed?
Question by: Shaun garfinkel on Mar 14, 2018, 3:50 PM
Hi there,
Thank you for reaching out.
The 20 inch Canister with 3/4" ports would be a clear canister with a black top. The volume of the cartridge that fits the canister is 109 cubic inches or about 7.55 cups.
It is the 2.5" x 20" canister found here:

Please let us know if you have any other questions.
Have a great day!

I am buying two 10 inch 1/4 inch canisters and am going to mount them to a one of your brackets. Do I need screws or bolts to mount to the bracket, and what sort of fitting do I need to hook 1/4 inch line to the canisters?
Question by: DARIN HIGGINBOTHAM on Nov 5, 2017, 12:13 AM
You will need four screws per canister and I have a link below to the proper screws. When it comes to the fittings, you have two options, a staright connection or an elbow. You will just want to make sure that you 1/4" NPT threads on one side and then 1/4" push connect fitting on the other side.

I have a Coralife Pure-Flo II RO Unit and the canister just broke, will these 10 in canisters fit that unit? I have a extra canisters but they don't fit, the threads don't line up so i am curious about these
Question by: michael on Aug 26, 2014, 4:02 AM
Hi Micheal,
I would have to assume that these canisters will not directly replace the canisters on your current RO unit. You should be able to unscrew the entire canister assembly from the bracket and install the new canister with lid. You should be able to reuse the fittings as long at they are 1/4" NPT threads.
This is the canister you will need to replace your broken one.
10" Reverse Osmosis Canister 1?4" Ports SKU: 200001
I hope this helps!

I have a 4 stage BRS RODI system and I would like to add another carbon filter, what parts do I need for me to do this?
Question by: JohnM on May 7, 2014, 6:01 AM
Hi John,
The simplest thing to do would be to convert your 4 stage RO/DI system into a 4 stage only system by rerouting the existing tubes (and removing the DI cartridge and replacing it with the second carbon) so that water travels through all 3 cartridges and then to the RO membrane. Then simply add on the "single DI" to add the DI stage back in. This way it comes out cheaper then purchasing all the parts individually and its a lot less work.

Answer by: Bulk Reef Supply on May 7, 2014, 6:01 AM
I have a BRS 5 stage (now converted into 6 stages) RO/DI, can the 20" canisters be screwed onto the 10" tops, and will it operate correctly with the 1/4 plumbing as I see the 20" canister tops have 3/4" in/out?
Question by: Gil on Mar 19, 2014, 7:01 AM
Hi Gil,
Unfortunately its not that easy :-) The entire canister (top and bottom) will need to be swapped out as the the bottoms won't thread onto the tops for the smaller sizes.

I'm looking for a replacement canister for a Pure Flo II RODI unit that cracked. Which canister would fit the unit?
Question by: Scott on Dec 31, 2013, 6:41 AM
HI Scott,
Most likely the canister you are trying to replace is a 10" canister with 1/4" ports. That said though, different canister manufacturers have different thickness brackets, canister tops, etc so while it will hold the cartridge and the plumbing should connect just fine, it may not work to put it on the same bracket.

I ordered the bracket, does it come with bracket?
If not, please advise?

Question by: Brian on Sep 7, 2013, 5:38 AM
Hey Brian,
Assuming that you are just putting this separate canister on its own bracket separate from the rest of the unit, your going to want a pair of fittings of 1/4" NPT x 1/4" push connect fittings (straight, elbow, whatever your preference). Assuming you want to mount it to the wall or something you would also want to pick up a bracket as well. Don't forget the filter you plan to put in it as well!
