Filling a DI Cartridge is easy. The most important thing to remember is to tightly pack the DI resin into the cartridge. Loose DI will cause the water to channel through the DI, greatly reducing the effectiveness.
Available in Four Sizes:
- 2.5" x 10" Cartridge (Standard - most used cartridge size)
- 4.5" x 10" Cartridge
- 2.5" x 20" Cartridge
- 4.5" x 20" Cartridge
NOTE: 99% of customers purchase the 2.5" x 10" Cartridge (SKU 200002)
How to refill an empty DI Cartridge
- Unscrew the bottom cap from the DI cartridge and remove the foam ring.
- Pour in the DI resin and pack it down tightly as hard as you can. Tap on a counter to help settle the resin.
- At this point the resin should be tightly packed flush to the rim.
- Put the foam ring back inside the screw cap and screw the cap on.
- Place the newly filled cartridge into the RO canister and make sure the arrow on the side of the cartridge points up.

Product Questions
Can these be used with kdf 85 and catalytic carbon to fill my own filters for my ro unit or are they only for use with DI resin?
Question by: Chris on Nov 23, 2022, 2:48 PM
Thanks for the question! You can really use them for all medias but you can use this one https://www.bulkreefsupply.com/brs-reactor-refillable-cartridge-hard-shell.html?queryID=6b81366fdeced9c5fdee0d1d0a90186f&objectID=1656&indexName=brs_prod_m2_default_products

Can you please tell me how many lbs of DI resin the 4.5"x20" filters hold? I'm guessing about 3lbs each. Thanks.
Question by: matt on Sep 13, 2017, 11:43 AM
The 4.5 x 20” DI canisters can hold just about 7.5 pounds of DI resin. It will take just over 5 single use bags or we would suggest just a single bulk bag of DI resin.

Does this cartridge need to be cleaned or bleached in between refills? If so, what is the best way to do this?
Question by: Cody on Apr 24, 2016, 9:36 PM
Great question!
These do not need to be cleaned in between uses and simply replacing the media is all that is needed.

I am wanting to buy the refillable cartridge and media for my DI. About how much DI resin fits into the cartridge? I want to make sure I buy enough resin.

Great question!
1.25lb refill will change one cartridge. I have included a link to the I resin below.

Will this fit a coralife filter?
10" seems a bit tall for my filter

Great question!
Unfortunately we are not familiar with the exact size of a coralife unit. These will work with most standard filter cartridges which are 10" tall from bottom to the top of the threads. Feel free to let us know if you have any further questions!

In order to change my DI resin, to I have to have the refillable cartridge?
Question by: Colton on Jun 20, 2014, 5:54 PM
Hi Colton,
If you want to use the loosefill vacuum sealed DI resin like ours then you would have to have a refillable DI cartridge (which is included on all of our RO/DI units). Some other manufacturers use sealed DI cartridges which can't be empty and necessitate the changing of the entire cartridge. If this is the case, just pick up a refillable cartridge and you are set.

What kind of connectors do these have?
Question by: Zach on Jan 17, 2014, 12:56 PM
Hi Zach,
These are just internal cartridges meant to go inside of the corresponding canister. The cartridges themselves don't hook up to tubing or have any fittings on them.
