crappy hydrometer, high salinity

so i was using the crappy plastic hydrometer, which i thought was working well. but my buddy brought over his new refractometer, which showed my salinity to be at 1.027 [ i know high]. now here is the question, since its been up that high my KH is at 13.8 my Mg is at 1200 and Ca is at 450-500 closer to 500 i think. what is going to be the best way to lower my KH? will it do it on its own now that the salinity is down to 1.024. i stopped adding my b-ionic. anything else i should do or just wait. on a positive note i now know why my sps werent happy.;D

 

Its not that high , But if you want to lower it in a 29 gal ? Just pull a gallon of saltwater out and pour fresh back in..

 

Mine stays at 27, no big deal, e-thing's happy

 

1.026 is nsw, dKH and Ca will lower on its own from the corals. Mg should be bumped up to around 1400-1500. KH or dKH, 9 dKH with 500 Ca is the correct ratio. 20Ca: 1meq/L or 2.8dKH.

rid yourself of the plastic floater, a glass hydro is a cheap and close to accurate way to go if you dont want to spend the money on a refracto

 

ohhh i m not worried about the salinity, it the KH that i am worried about, i thought it was supposed to be around 9 mine is at 13.8
