Why is this brain-dead idea for saving water one for failure ?

In your case, the goal is to recycle your water with as little wastewater as possible.

The mixed-bed resin reduces the water hardness to 0% if you want. You can reuse all the water, and since your water already contains few salts, it's an economical method and far less complicated than what you're planning.

Theoretically, organic contaminants would still need to be oxidized, but in practice, I haven't noticed any negative effects when using resin in the filter chamber. However, I do have heavily planted aquariums.

I have a wide range of aquariums - still there might be stuff in the water i want the ro membrane to filter out before sharing it with other aquariums.

You can use resin directly in your aquarium.
Put it in a nylon stocking or whatever and then in the filter chamber.
I did it a lot in the past, but now my filter is full of monstera roots and it's not so easy to change something.

I'll have 25 aquariums; do you really think i want to put resin in 25 different aquarium ranging from 600 gallons to 10 gallons and keep track of each one ?

I don't understand your problem to be honest.
I tried to find a water saving solution for you, because i thougt that it was your main interest.
RO with ratios like 1:1 will not last very long except the water is already soft.
Filtering water from your aquarium with RO is unhygienic in my point of view. It will also destroy the membrane, because some bacteria can "eat" the material it is from.
If you have a filter in this aquarium, it is very easy to make it like i suggested. You need only a tds meter. But if you think I'm crazy and don't know what I'm talking about, it's no problem, i will keep my mouth shut, next time you ask a question. Works great for me.

I have a solution to the bacteria problem.

For sure, you can try it. Looking forward for a review i just think it's way to complicated.
But that's only my perspective, i could be completely wrong for sure.

FWIW (in case you are new to RO) don't neglect to change the pre-filters. I was shocked at how much visible muck came out of them after 6 months from only mechanical filtration. So much so that I will never drink tap water again.

I change mine every three months . Sometimes the sediment filter still looks new and sometimes it looks brown and clogged . City water supplies can vary for many reasons . If you have a water main break nearby you will get a big rust and crud surge that will foul things . Also , the carbon filters save your membrane . Chlorine kills membranes fast .

I use large pre-carbon containers prior to the ro unit - they can filter 20 million gallons before i have to replace the carbon.
