Unless you are having major issues I believe you posted your Alk in Meq/L (2.8) if thats the case then your PPM is 140 and your DKH is 7.24 all are a tad low.

okay i am due for a water change tommorow will this raise my levels
and what math conversion did you use to get that number

 

[louti]

to convert from ppm to dKh, divide by 17.9.

 

[perfectdark]

Meq/L X 50 = ppm
Meq/L X 2.8= dKH
Alternately
PPM/50= Meq/L
dKH/2.8= Meq/L

okay now i am confused my marine test kit says i am in the high normal @ 2.8

The ideal range for alkalinity is 7 to 10 dKH, when I said you were a tad low I should of further explained. Your alk is not dangerously low but target areas in that range tend to be in the 8's or 3 to 3.5 meq/L. HTH and yes a water change would most likely bring it up. I wouldnt do anything until then and then retest.
