Is it worthwhile to let city tap water treated to .5ppm chlorine levels (not chloramine) sit out with aeration rather than using prime or safe in order to keep TDS lower? I imagine the dechlorinator adds some additional dissolved solids that Rams don’t need? If I let the water age with aeration, how long does it have to sit before using it to do a water change? Letting the water age is also beneficial because the Ph drops from 9 to 7.5 in 24 hours. Since I want to let it age anyway, why not skip the dechlorinator?
