Couldn't find the regular one and on reef central they had a test and said it comes out to 8 which is better than my 11 but I guess next batch will get some muric acid to lower alk
Do you have a link on reefcentral about Red Sea coral pro salt? According to the manufacture, as well as my experience with them, at 1.025, it should have about 12 dkh
Calcium test kit can have 10% error. You may be well over 500 ppm. Even at 500 ppm, when you put in salt water with Alk at 12, (that is where Red Sea pro suppose to be at), you get a calcium carbonate storm.
