By all that I can find out, the TDS to uS (micro seimens) conversion is basically that TDS converts to 1/2 the uS amount. (uS X .5 = tds)
MY RO system puts out a consistant 4 ppm TDS, so that would convert to approx 8 uS ??
That seems to be a bit marginal for where most the Paros are collected,is that true or are my calculations off? or would it be ok for them…it seems PH is the most important of the water parameters or successful breeding.
