You got 200 ppms of hardness what ever that means. They should state if its calcium or magnesium or both. I would call and ask. 200 ppms ca or mg is alot of nutrients in the water and you should change your feeding plans accordingly for few problem plants.
go online to your city or water district wedsite and look for the annual report. on my district's website its in the publications section. water districts are required to provide the info to the public free of charge so your city or water district will certainly have it on their website becuase that is the cheapest way to make it available. i had to search around for a bit until i stumbled across the publications tab, which in retrospect seems obvious becuase the annual report gets published. my water district breaks down the total hatdness into calcium and magnesium but not all districts do becuase state regulation differ from state to state.
Total disolved solids (TDS) is 330 - I wouldn't use it if you've got another water source available. If you have to use the tap water, go easy on the calcium suppliments/nutes. Rain water is usually very clean if that's an option for you.
