I assume you aren’t using RODI (reverse osmosis deionized) water? You may want to research this topic more as it is typically considered the standard for saltwater aquariums. When using RODI you don’t need water conditioner.
It is usually safe, unless your water source has heavy metals. The bigger issue is typically phosphate and/or silicates which can cause terrible algae problems. If you can find your city’s water testing report or have an icp test performed it would tell you for sure what in the water. If you can borrow or rent a tds (total dissolved solids) meter that would be another way to determine if you want to use your tap water or not. There are RODI systems under $100 if you want to be sure you don’t have contaminants or unwanted nutrients in your water. I recommend making your own saltwater. If there is an emergency it can be the difference between saving your livestock and a total loss.
It's safe. I went RO/DI and still had a horrible case of the uglies, which I am still fighting after 5-6 months if I am honest. I am only now getting on top of it. Your tap water probably has good minerals in it, as well as phosphates and silicates. If you have already used it, treat it and go. Here, to my shame, is my 5-6 month reef. I still have some hair algae, and the little white curly worms everywhere. My livestock are doing well though. All the white on the rock? Used to be fake purple. Cleanup crew ate it all off!
In an emergency Tap is acceptable but should be avoidable. RODI or spring water is best bet(s)
I know of a few that utilize tap... all depends on your local source. Hard? Soft? Plenty of variables from there....might end up working out, never know.
It'll be great to figure out a healthy flow for my tank. I've been researching and for a month ½ and finally decided to take the first steps for my fish-only aquarium. I hope yours clears up soon! I was thinking about getting cleaner shrimp at some point, well after the tank has been established.It's safe.

Time is the only cure. My cleanup crew have been what I watch. My clowns have hosted to the heater. Been reducing nutrients as much as I can, skimming and filter media changes. If you are aiming for FO, you will do fine. My goal is some softies. As it stands now I have a tank with 2 clowns and a Coral Banded Shrimp who thinks he is King.
