Hello everyone, I've come across two designs of the Red Sea blue bucket salt, but not sure which is the current version and which is the old version. One bucket gives measurements for 35.5ppt where the alkalinity is 7.7 dKh, the other design gives measurements for 35ppt where the alkalinity is 8dKh. Help!!
This one measures 35ppt and alkalinity is 8 dKh
This one measures at 35.5ppt where alkalinity is 7.7 dKh
