My betta tank has high alkalinity & hardness but normal pH. Is it bad?

Question

Hi, I just tested my betta tanks water & his ph is good sitting at 7.5. But my alkalinity & water hardness are both very high at 720 ppm (alkalinity) & 300 ppm (hardness). i’m just curious if i should be concerned since my ph is normal. Pet's info: Fish | Betta | Male

Thanks for reaching out about Snow. Chronic high alkalinity and hardness can expose to fish to high levels of minerals that could lead to abnormal mineralization/calcification of gills and other orders. Test your tap water and if also high, which is expected, than bottled water might be in order. Good luck.
