Low Carbonate Hardness-Is it a problem

[Genesis]

My 10 gal tank is just short of 2 months old and has the following water params:

 

Ammonia=0

Nitrite=0

Nitrate=0

PH=8.2

Phosphate=0

Calcium=440

Carbonate Hardness=6 dkh

SG=1.025

Temp=78.5

 

To me it looks great with the exception of my carbonate hardness, which seems to run low.

I am using distilled water with no dosing of any kind and would like to stay away from dosing. I currently have no corals but will be adding soft corals and a few LPS. Is the low carbonate hardness going to be a problem?

 

Thank you in advance for all advice.
