My Alk has been 12 or higher for the last 6 months. Hasnt had any noticiable benefit so I am going to drop it back down. Have tried as high as 14.
On the other hand, it didnt cause any trouble except on one SPS that i bought from the LFS which they kept at 7.5 Alk and it went through a rough adjustment. Its doing fine now too.
Im going to let it gradually fall back to 9 over the next couple months.
