Tap water contains various salts which may precipitate on leaves. That's not a very serious problem, but if you can avoid it, you'd better do.
Are you using plain silica sand or some of the commercial substrates?
Frankly, I've never had an opportunity to get acquainted with Tropica soil. Yet I suppose it's similar to other commercial soils & substrates.
These substrates contain lost of nutrients which leach easily as well as easily degradable organic matter. Both contribute to 'microbial storm' lasting several weeks when many water changes are necessary to overcome this period.
If you do a dry start which is, in fact, a wet start, that flood of nutrients and microbes will occur, too. And that's definitely not the right moment & place to introduce any plants.
Well, my opinion. Others might think differently, or possibly know how to handle it.
