Angelfish and water parameters


I am in the process of setting up a new 55 gallon tank. Currently, I have a 20 gallon tank (I've had it for 2 years) and I recently added in some live plants. The water parameters in my current tank are as follows:

Nitrate - 20 ppm
Nitrite - 0 ppm
Hardness - Very Hard
Alkalinity - 80 ppm (test kit says to add buffer up)
Average PH - ranges between 7.2 to 7.6
Ammonia - 0

I do a 33% weekly water change and my current list fish-friends includes 6 black skirt tetras, 1 cory and 1 pleco (my clown loach died last week, very sad as he was my favorite fish).

My question is this: Can I have very hard water and low alkalinity at the same time? I've tried understanding how alkalinity and water hardness effect each other...but I'm just not getting it.

Eventually, I would like to move my current fish into the new tank plus I would also like to add some angelfish in (maybe 4) and some clown loaches.

Anyway, if anyone can tell me whether or not I should try to adjust the alkalinity of the water and add "buffer up" that would be great. Also, will this lower the hardness of the water or does it even matter? I assume that once the new tank is up and cycled the water parameters in the new tank will be similar to my current tank. This is why I'm wondering if I should worry about the current alkalinity and hardness.

Thank you in advance for your advice.
