Curious to hear how many of you use liquid vitamins to add to your tank or foods as a supplementary diet for your fish.
Has anyone had any problems with their water composition after installing the liquid vitamins? If yes, please give details.
Even if you don't have any problems, please share your experiences.
I've got a bottle that is ineffective and filled with bacteria. I was told it is the culprit of my water composition being so high (filled with nitrates and other stuff). The bottle was purchased last year (summer). Some feel it should have had an expiration date and even refrigerated. How do you feel about it?
Thanks a million!
