aquavitro calcifacation question

[ls1boost]

I have used some of the aquavitro line in the past not as regular as I should I guess but I purchased a bottle of the calcifacation today at a local store. I took it home and was going to add it to the tank and it was a brown color almost like the fuel it has been awhile since I used the calcifacation but I thought it was clear. Has anyone seen this or did they change it?

The color can vary some from batch to batch. Also, the gluconate component used in this product can darken over time. This will not reduce it's effectiveness nor will it effect the calcium concentration of the product. Please let us know if you have any additional questions
