What's the way to go with a DI cartridege?

Standard color changing?

HI S color changing?

Refillable cartridge w/separate DI resin?
 
Bulk Reef Supply, as well as The Filter Guys offer several choices, all of them good - you may want to ask their advice for which specific one to use.

IMO I like a color change, mixed bed resin. If you install a TDS in/out meter, it will tell you - possibly before - the color change occurs.
As well,do you need silica removal? Have you tested your source water and found them high in silica?

i like the refillable cartridge and i also just go by my tds in/out meter. i feel it's very reliable and lets you know what your tds reading is. their is also air water and ice. com.for another good store.
 
Yep...good point.
As well - you can buy the "non-mixed bed" resins, which are the Cationic, and Anionic and set up 2 canisters. The advantage is that these can be re-charged many times before exhaustion.
If you are using the TDS meter for in-coming/out-going measurement on your DI, then you can monitor how long they are lasting between re-charge, and determine when to replace them as well.
