Just wondering how people here look at the TDS readings and how they affect your fish. What are peoples options on lowering TDS, R/O units, what else? The little bit of reading I have done seems to show that low TDS will produce a lean fish that grow fast, where as hi TDS will produce fat fish with slower growth, i.e. my pond My well water right at the expansion tank is 383, my pond is 429, and my tap water inside the house using a water softener is 539.
Do these numers go side by side with ORP readings (don't have a ORP meter yet)?
