(There's a good article in the May TFH about the benefits of water with a low conductivity.) When I replaced my r/o filter last fall, my r/o water was much softer and more acidic, and fish that looked dull and nearly lifeless started to glow and spawn. The cheapest and easiest method, I feel, is an r/o unit. Sure it's going to cost you at least $100, but how much have you already sunk into your hobby? If you want success, you best do it right. Plant people invest in quality lighting and CO2 injection; Apisto keepers ought to invest in an r/o unit (or de-ionizer). - --Randy
