Ok, would not recommend dip strip test kit tbh as not very reliable.
You would be better off getting API Master Freshwater Test kit as it’s more accurate and reliable as well as being cheaper than strip test kit in the long run.
And it takes more than just letting the tank run for a week or two with snails and shrimps to cycle the tank and adding fish food as a source of ammonianis
Really is not as simple as that. If it was LFS or another website that said this then this is just simply bad advice.
If you were to add fish now or next week, I can guarantee you that they will sick and likely to die due to ammonia and nitrite poisoning.
So please read the fishless cycle article that I linked earlier.
Following my advice really will save you a lot of trouble and hard work, a lot easier to cycle the tank first before adding any livestock.
So, first is to get the test kit, then would purchase some bacteria starter such as one of the two recommended Tetra Safe Start or Dr Tim’s One and Only Nitrifying Bacteria.
That will help you get a nice start in getting the correct bacterias into your filter and tank, quickens the process by a week or two, worth it.
And also you will need a source of ammonia, much easier to calculate dosages with this rather than algae wafers or fish food as it’s important to dose 3ppm ammonia otherwise you run the risk of crashing the cycle and then having to start over again.
A lot of information and advice to take on but this is the correct way of doing things.
By the way, I’d recommend you take the shrimp back or rehome it as it’s very unlikely it will survive the cycling process am afraid, shrimps are much more sensitive than fish to water parameters.
