Has anyone noticed or have had this happen? This is the second bottle I’ve open of RS Reef Foundation A (calcium) that has a slight discolor to it (brown). The first one I was able to get a replacement. However, I am going out of town literally right now and just poured in a new 500 ml into my container. I don’t have time to run out and get another bottle. Is still safe to use? I will be back tomorrow. I daily dose about 9 ml of Cal a day. Doesn’t smell bad. I do notice some solids on the bottom of the bottle?
