I personally recommend this :
Seachem MultiTest Marine Basic Test Kit
https://www.amazon.com/dp/B001EUE8EY/ref=cm_sw_r_cp_apa_2lxrzbRJV1H1E
I prefer this tank for nitrogen related inspection (ammonia, nitrate, nitrite).
Get everything in check via nitrogen, and after your tank is cycled, start focusing on alkalinity. This seachem test kit will get you into the ballpark.
And then once that is in range, bump up to the red sea foundation.
Red Sea Reef Foundation Test Kit - Calcium, Alkalinity & Magnesium
https://www.amazon.com/dp/B004FUJ5NE/ref=cm_sw_r_cp_apa_qoxrzbDJ28MSP
This will get you much closer to the ranges you need.
No one ever makes a good alkalinity test using visual reagents, so...
Once you have those dialed in, purchase a hanna alkalinity checker for $50.
This will be an expense spanning about 3 months, about $130 in all, but they are all very handy to get you to the point of dialed in water parameters.
