Need DI resin

[newsalt]

I need to change out my DI resin and want to purchase some. On the Spectrapure website, there are several types: color indicating, non-color indicating, anion, cation, etc. What is the best one to get for an RO/DI unit for a reef tank?
Thanks

If you only want to use one cartridge, the Silica-Buster is the best choice.

From the web page, http://spectrapure.com/St_replac_p5.htm :

Each DI cartride holds 1 qt of resin. 2/3 of this cartridge is our Silica-Buster Mixed-Bed resin and 1/3 is Strong-Based Anion Resin.

It's your choice to use indicating or non-indicating resins.
