Lol. That's not RODI, if accurate
Therefore you are adding Alk every time you top off for evap (and who knows what else?)

Ok, so out of curiosity i have just tested my ro water and my salt mix. Both are bought from my lfs, been using them for years, freshwater and marine. The manager, Sam, is an avid reefer who always has time to help out with any problems, however, this is baffling him too. So, here we go with the test results.
RO SALT
Nitrate 0 0
PH 7.4 7.7
phos 0 0
Alk 5.1 10
Mag 0 1260
Cal 0 470
Sal 0 1.025
And my refractometer was calibrated prior to this test. Dont know if this is relevant, but there is some algae on the inner walls of both my ro containers, but not on my salt containers. It is not very noticable till i look closely. Hope something here helps to solve this. I stated earlier that i had done 25ltr water changes over 5 days this week, my mistake, it was 50 ltrs.

My freshwater water tank is HDPE
It can form a thin slime layer inside, bacteria
I just cleaned out some aspergillus(black shower mold), fungus
My thinking is that it's just metabolizing dust. Most indoor dust is dead skin cells, so that tracks
They could be eating the tank plastic, I tell myself "nah"
It also tracks that you could have fresh water algae. It blows around in the air.
Don't use anything toxic to clean it. I use vinegar and sodium bicarbonate only

No organisms are eating HDPE.

For what?
An alk titration works perfectly well in fresh water. The Hanna may not.
