RODI system w/ chloromines

[jstephens24]

So I currently have a 4 stage 75 gal per day RODI system from BRS. It has been in storage/garage for the last 3 years so I was going to just replace filters/ RO membrane and upgrade it to 150 gal per day with another RO. After doing some more research and looking at my city's water quality report it looks like I need a 5 stage RODI system. The 2018 report showed 3.05 ppm Chloramines and TDS 217.

Just bought a WB 220 so I want to start everything on the right foot and since my city uses chloramines that means I need a 5 stage unit. My plan is to have coral eventually.

just buy the di upgrade instead if the whole unit. Brs sells them. Works great for me

Sorry. My brain shut down. You’ll want a new unit. A 6 stage is what you’ll need.

Yup, 5 stage is correct. If u still have questions, email BRS and they will confirm what u need.

BRS chat person told me I should just add another carbon block to my 4 stage which doesn't make to much sense to me. Looks like I almost actually need a 6 stage. 5 stage is for small amounts.

edit:He sent me a link to extra housing to buy and in that description it says to use 2 carbon filters to remove chloramines so looks like that might be the answer

Then that's what I would do. GL
