Hi. Welcome to the hobby. After reading your post, here are my thoughts:

Your tank is not cycled and is not ready for snails, fish, or coral.
If you have ANY chlorine in your system, it is toxic! (I don't understand the strips you refer to, but it appears they are for swimming pools??)
You don't need to even THINK about dosing this early on.
I've never heard of "ro uv water", nor "instant coral salt".

You seem to be moving too quickly and should try taking a look at some of the sticky threads about cycling and starting a new tank.

Hope this helps

The water I am referring to is from Primo. Reverse osmosis, carbon filtration, and uv sterilization. Test strip pictures attached, they are for fish, not pools. I should have put, Instant ocean sea salt, in my defense, I was tired. I have been reading the threads and doing what I thought was right. I don’t plan on putting in anything until it is cycled. I appreciate the input, however you didn’t answer the questions I asked. I need help.
