RO/DI refill cartridges

[Munch]

I have a Spectrapure RO/DI unit, I've purchased their resins in the past to refill my own cartridges.

Should I continue to goto Spectrapure for resin supplies? Or is there a better/more cost effective option?

Dont know how the different brands compare, but I use BRS color changing resins in mine. It last quite a while and turns from blue to brown once its expended.

I can't seem to locate all the kits on their site anymore, just the DI resin, at the bottom:

Looking for the Silica buster stuff too, can't seem to find it

Do you layer it, or fill your container with one product? The Spectrapure is two medias in one container, 6" of one, then filled to the top with the other...

one Product, just pack it in super tight

How many stages is your system?

Mine is 4, with the first two being paper type filters, my last two are filled with media 1: Silica Buster 2: DI

Doesn't look like BRS sells a silica buster equivalent.

That i believe is a 5 stage RO you have, I have a 4 stage though. I think at least with BRS for the 5 and 6 stage rodi they use different levels of carbon blocks instead. Although I think you could try 2 of their resins instead of carbon blocks

Ah ya, the top is another stage

Guess I'll give the BRS stuff a shot!

I would be curious to hear your comparison
