Upgrading my RODI unit. Needing more water capacity

[Legonch]

Ive been searching the internet tonight, but not finding much info on upgrading my RODI. Its a spectrapure 5 stage, 90gpd unit. Anyone know how to double the capacity to 180 GPD? Im trying to find a membrane and flow restrictor kit, but no luck. Thanks!

This is the one I have and really like, I added it to a different brand RODI filter than the BRS one and it works perfectly. Not sure you need to use Spectrapure stuff exclusively, but this one worked for me!
