I am switching out my CARX and Kalk for 2 part. I set up my DOS and reservoirs. I am using Seachem Reef Fusion 1&2 since this is what I have used before. I had 2 4L jugs in storage that I plan on using.
I poured the jugs in and the calcium appears to be this brownish color. I dont remember it being this color. Is it safe to use or should I just get a new one?
