New Pool, Well Water and should we worry about Calcium

We are hoping to start filling our pool tonight or tomorrow night. We have well water that is very high in mineral content. I tested our water using the TF100 test kit and also ran the numbers through the pool calculator. Our pool is vinyl, Intex Ultra Frame 16x48".

My questions:
1. I believe we have metal in our water. How can I test for it?
2. Should I treat for calcium?
3. Our local pool store says they don't sell dichlor, only trichlor. Is it okay to use trichlor instead?

FC <.5
ph <6.8
T/A 30
CH 150
CYA 20

Thanks so much!

You tested your tap water? Tap water doesn't contain CYA...
You will need some Borax and Baking Soda to raise your PH and TA
Do they have trichlor powder granule or trichlor tablets?

Yes, I tested our tap water which I thought would be the same as our outdoor faucet water. Is it different?

I'm not sure if it's trichlor powder or tablets. Is one better than the other?

Any thoughts about testing for metal?
