Started a manage shrimp tank last week along with a 2 domino damsels and one morning I did a salinity test and it shot up to 1040. Reasonably I started panicking , and since I had no conditioner on me. I removed about half of my water and dumped in freshwater strait from the tap. I know this sounds stupid, but I tested my tapwater and it came back no nitrates, nitrates or ammonia. What I didn’t know was I had to wait. I only waited for a minute. ( that’s what was recommended.)
But as I wrapped up, I came back to look at the test and it shot up to 50 for nitrates 10 for nitrates and five for ammonia (it didn’t give me the unit of measurement) I immediately bought and used beneficial bacteria did a 10% water change. It helped a little bit, but I’m not sure if I should take all of the water out and restart. it is probably worth mentioning that I have a 30 gallon tank and my mantis shrimp is showing signs of molting. at this point, I am so confused. I’m not sure if I should just quit and pass it on to someone else. I am really confused and now I see why shrimp isn’t recommended for beginners. It might also be worth mentioning that this is my first saltwater tank and any fish tank in over a year. also, I’m not sure if he’s molting or just adjusting because they had him in a one by one before I bought him about the size of someone’s face. please let me know what I should do. i’m currently debating between a full water change, plants, or giving up. :(

Please someone help
Ideally, get the livestock back into an actually biologically cycled marine aquarium ASAP (maybe your local fish store?)! then, do some research on the chemistry of chlorine in tap water, and how the nitrogen cycle works!

Ok, biologically cycled fish tank you mean one with benifical bacteria, filters, and ammonia being turned into nitrites to nitrates right

I recently put in beneficial bacteria that start the process I think two days ago, the fish store had him in a cube that looked about 1 gallon. No decorations nowhere to hide they didn’t let him eat live food. i’m scared to leave him back to the fish store

If I buy salt water and buy a decently sized tank, can I put them in there while the tank settles?
No, do not add livestock to a marine aquarium while it is cycling. Ignore products that claim to instantly cycle the tank. This hobby takes time, and invertebrates especially should not be added to a fresh marine aquarium.

as I have statedbefore I have no place to house them while I wait for it to cycle. You might have misinterpreted my question if I buy salt water that has no nitrates nitrates or ammonia and let them quarantine in there while my tank cycles will that work

In theory, if you do a LOT of water changes, yes. What are you using for biological filtration?

I’m not that experienced so I’m assuming you mean like beneficial bacteria and bottom feeders if so, I got snails for free and I use beneficial bacteria
I mean the material on which the beneficial bacteria will colonize during your tank’s cycling period. I.e.: substrate, porous media in your filtration system, coral skeleton (aka live or dry rock), etc…
