after meeting with john today, i learned that i should start testing for alk if i want to keep sps. since today ive never tested for this or knew too much about this. i went home and looked through my misc fish box and i found an aqua pharm alk test kit that i didnt even know i had. according to the test (if i did it right) my alk is around 6dkh. wanted to know if this is good or bad and how people go about correcting it.
