Rodi/ osmose

[Kobe V²]

So i bought a osmose device 2nd hand but i didnt get al lot of info about it.
I asked on a Facebook group and a few people said it was a good device and some said it isn't such a good one.
this is the device: https://www.poisson-or.be/nl/osmose...rsion-pro.html?search_query=osmose&results=88
this is the TDS meter i got, the tunze dual TDS meter 2 : https://www.aquastorexl.nl/tunze-ro...88KtfUQCQwSrk3k9ghebJl2lvlkyLVScaAr8lEALw_wcB

The tds meter says my in water is 520 and my out of water is 7
How can i lower my out number ? and is it a good or a bad device ?

Thank you very much!!

TDS meter is perfectly fine. The unit is likely a fine device- you will likely need to replace both your filters, DI resin, and possibly your RO membrane depending on age/use (start with filters and DI resin). You should notice your TDS value reduces with new filters. I wouldn't jump to blaming the RO unit

I am new to the hobby (9months)
So 4 and 5 are the filters i gues?
3 is the DI resin?
1 the RO membrane?
And what is 2 ?

1) RO membrane
4) Says Carbon blocks- I would confirm that is accurate. I would need to see what is feeding them as usually the sediment filter precedes the carbon block. Complicating this is just because it says carbon block, doesn't mean that's what's in there. Easiest way is to open them up and look inside. It's possible 3 is a sediment filter- if you can read it or get a better picture, it will be easier to ID. 3 Could also be a DI resin- see below. Can you tell me which number you first encounter if you follow the line connected to your water/faucet?
5/2- possibly DI resin? Easiest if you're able to open them up. Generally speaking, the DI cannister is last, so if you follow your outlet tube (not the wastewater tube) you can follow it to the DI tube. If it has a beaded resin, you've found it!

Metal- RO booster pump

water should go from:
Water source
5 sediment
4 (both) carbon
1 RO membrane

Then to DI. The 3 could be DI, and I have never seen an anti scalant before, so I can't comment

So this is the way its flows en then a pic of the di i think
The first filter is just for big particles
