RO/DI Replacement Filters

[NDIrish]

Need some experience advice on RODI filters.
I have a 5 stage,100 gpd system. I think it is a Premier Purity system. There is a Premier Purity sticker on the inline carbon filter, which I discarded.
I have the system for 8 months now. I just replaced th DI resin. I don't know how old the other filters are so I want to replace them. I don't know what micron to use.
Water out of my faucet has 43 TDS.

The existing filters are:
1st - 5 micron sediment. Want to replace with 1 micron filter.
2nd - GAC filter. Replace it with 5 micron carbon block.
3rd - 5 micron carbon block. Replace with 1 micron carbon block.
4th - Vontron ULP2012-100 membrane. Website shows it is .0001 micron.
If it is .0001 micron, I'll replace it with another Vontron. If not, I'll. replace it with 1 micron.
5th - DI Resin.

What is opinion of my replacements?

Thanks

definitely go to Bulk Reef Supply for replacements.

First, depends on incoming water. City or well? Chlorine or chloramines? Also if you go to small a micron, you may lose the water pressure the membrane needs.

Edit - if you call one of the places specializing in rodi like buckeye or air water ice, they will be able to tell you the best recommendations.

Do you think my replacements are in line?

City water, chlorine. 43 tds.

If you're sure its chlorine and not chloramines (if chloramine you will need a catalytic carbon vs carbon block) 10 micron sediment, 5 micron carbon block, 1 micron carbon, and replacement ro membrane of the same size.

are you trying to improve the life of the resin or improve the life of the membrane?

I looked it up on the water company's web page, it stated they treat the water with chlorine.

Life of membrane

In that case, tightening down on the inlet should do that. You may sacrifice some membrane performance and hence, resin life. It would be interesting to compare, but in the end, things like contaminants, temperature, and pressure make it hard to know unless you see a huge difference in lifetime. I think you can go with your plan, but if it were me, I'd try to keep track of how its working. If you lose much resin life, you may find its worthwhile to switch back.
On another note, I've found that websites have pretty generic water treatment information. I'd encourage you to email or call the water treatment office - sometimes they use terms like chlorination and sterilization generically.

Wow, 43 tds. Mine is about 120. My water is also chlorine. I have a 6 stage BRS system. I make several thousand gallons per year. When my sediment filter gets kinda tan, I change the sediment filter and my two carbon blocks: one is a 5 micron and the other a .5 micron. This takes 6 - 9 months. I have changed the RO membrane once after several years. I flush it before using it.
