So I recently switched from Red Sea Pro salt to Fritz Blue Box salt. I have a 75gal tank and do weekly 10gal water changes, admittedly I have been slacking on my water testing and recently noticed many of my hammer corals contracting and not looking well. I decided to do an alk test and noticed my alk has fall to around 7.6 from 9.5 when i used red sea. I also hadnt been dosing as with red sea I never needed to. Ive started dosing again and am slowing getting my alk back up. But with that said I decided to test my salt mix before putting it in the tank and noticed the alk to be 6.7dkh. Has anyone else noticed Fritz blue box to have this low of alk?
thanks
