As long as you use tap water you will have phosphate. It comes in in the water.
The grocery store RO is much better than tap not as good as RODI but it will work temporarily.
You can, in the future help your fish, by providing an environment that is as low stress as possible. That means lots of rock work for them to hide in. This will also provide a good surface for biological filtration. Don't over stock the tank. Don't put fish in tanks that don't have dimensions that are consistent with those fish's swimming habits. Volume isn't as important sometimes as dimensions. QT all fish at least 4 weeks before they go into your tank.
