I'm currentlyon debate on getting a water softer and a r/o water system for drinking and for my fish. from my understanding r/o water takes all traces of minerals and whatever is in the water... so that leaves the fish with no plain water w/ nothing in it... is this good? what about electrolytes? and water softer actually puts some salt in the water in replacement for the magnesium and calcium (these are two elements that contribute to scalling, hard water and lime build up everwhere their is water)
