How do I replace my RODI filters?

[Leon Gorani]

I have this 5 stage rodi system from bulk reef supply :https://www.bulkreefsupply.com/5-stage-premium-plus-ro-di-system-bulk-reef-supply.html
I also have the water saver upgrade option but i think i need to replace my filtration because my tds meter is reading 3 or 4. I just need some help figuring out which filter goes where and how to replace them correctly. Here is a pic of my rodi system for reference. My last filter on the far right, I'm guessing thats the DI resin, is red and i think i need to replace that. How is that done? is there a video on how to replace it? Or do i just empty it and put in the Blue Mixed Red DI Resin from this replacement kit into the last chamber?
Also is this the correct replacement kit for my system?

Does the "Blue Mixed Red DI Resin" go into the last chamber in my system?
I have never changed any of these so I don't want to put the wrong filter in the wrong chamber haha.
Im guessing the micron sediment filter goes in the first chamber on the left?
Also when do i need to replace the water saver filters on the top? Can you please paste a link to those replacements since I'm not sure what they are.
Thank You!

This is the order from left to right from BRS
Recommended installation for this package:
Stage one: GE ROsaves.Z 1 Micron Sediment Filter
Stage two: BRS Universal 1 Micron Carbon Block
Stage three: BRS Universal 1 Micron Carbon Block
Last stage: DI Resin

The RO membranes usually lasts a couple of year

Looks like the di stage is depleted and needs the resin swapped out.

How old are the prefilters?

That’s what I thought. So I just replace that with the bag of blue mixed bed di resin in that package I posted? I haven’t changed anything since I bought the whole system back in July of 2019.

I would order that replacement package. Change out the prefilters and di resin that comes in that package.

I try not to let my prefilters go longer than 8 months. 6 months is typical for me. The di resin, I swap as needed. Based on tds reading and/or amount of color change that has occurred. If 3/4 of the canister changed color, I swap it out.
