Thinking again...
There is a much simpler way to know that there aren’t any bacteria’s or algers or funguses in the system... don’t know why I didn’t think about this before... (And I don’t think its necessary for a sealed system with no UV-lightning if the loop is inside the case but if the water is exposed to light (UV-lights or sunlight) or open air, then there might be reason for distilling the water...
I have some fishponds (about 65 m^3 litre), and I use UVc light to kill algers (Have a 25000 lph pump)... A cheap UVc lamp cost around $30-40 with holders (my cost about $350 with some magnets that even have a warning label that says "keep as far away from the body or something like that) .. It "doesn’t" affect the flow rate nor any other parts (the light is almost sealed inside due to absorption)...
Edit: With this type of rig the only additives that should be required is anti corrosion
