RO and DI?

i have heard of a DI only but never an RO only system.

 

HAHA good thinking... Honestly, I would buy all equipment offline, and all emergency/livestock at a reputable LFS... They are sooo marked up, as you have learned...

Best of Luck

 

The Filter Guys . Biz

 

airwaterice.com is pretty darned good too.

 

Sure you can get either or as a stand alone filter , I prefer a mixed bed resign for the D.I that way its just on canister to deal with . If you already have a R/O then simply add a D.I at Buckeye field supply they send the D.I with bracket and fully charged and ready to go for 35.00 or so I think it is ?

 

+1 on tangsters comment, they deff sell components alone, just ro and just di. best to runtogether. if you just have a ro unit deff get a di chamber, it will bring your TDS to 0.
