"I can use a tap water conditioner instead of chemicals in a RO / DI system?

My question is, why I can not use a conditioner tap water, such as the Aquarium Pharmaceuticals Tap Water Conditioner, or Top Fin water conditioner instead of buying an RO / DI water system for my nano reef? If the RO / DI system is designed to remove all minerals, etc, and chemicals to do the same, what is the difference? Thanks in advance for your help.

But any nitrate or dissolved minerals found in tap water are still there. RO filter basically removes everything from the faucet, leaving than pure water. Then you can add the proper chemicals to get your artificial seawater Ian
