As some of you know I recently had a major issue with doing a large water change and lost some corals due to not testing my make up water before the change. My question is what are some of you experienced guys using for salt and how often does something happen like this? Keep in mind I have had this tank running for almost 4 years but switched from fowlr to reef about 2 and a half years ago. I have been using red sea pro salt and not had any issues before but I will admit I was not very good about doing water changes and when I did they were smaller 5% or 10% changes. I will not judge this brand of salt on one bad experience alone but for now I am switching and testing every batch. I was thinking of trying Seachems reef salt. Thanks for your input
