My Dad and a few people I know that have fish tanks, just add water, conditioner, and fish all in the same day. The fish always survive and I can even say thrive. Now my Dad has kept fish in the past and this is how he's always done it. He also does water changes when the tank smell or the water isn't clear, not weekly. No test kits, just goes on plain instincts. Makes me wonder if we fallen into the marketing scheme of "You need this and that or you fish will die" propaganda. I think fish keeping used to be simple as that, but somewhere along the lines things got more advanced (complicated). I don't know...just makes me wonder about how we obsess over telling people that they need this or they need to do that. Anyone else ever feel this way?
