[Killietalk] What am I missing? (RO/DI Water)
Maybe someone can explain this to me as I'm relatively new to killis. I learned about RO/DI through reefkeeping in which anything above 5ppm TDS is considered dirty. Redundant DI's, .5 micron prefilter/carbon blocks, and 98% rejection membranes are commonplace. I've never heard of anyone mixing with tapwater or adding chemicals back to the pure water (except sometimes calcium, iodine, etc.).
Why is it that most freshwater hobbyists seem to re-contaminate their pure product water by adding tap? What magical ions do products like RO Right add to the water? Is there any science behind it, or any way to verify the claims?
>From what I understand, the common belief is that pure water is unstable PH wise. FWIW, I've been using 0 TDS water for bettas, killis, etc. with no problems so far. So if pure water is desirable for super sensitive reef critters, how can it be bad for killifish?
