Review on API Freshwater Aquarium Raising Solution by Melissa Marie

I have had aquariums for many years which have taken very good care of my Oscars, goldfish and tropical aquariums. Years. But I know that there is something wrong with this substance, I have to put more in the aquarium than usual, in a week I have to add more. What's up with it? I genuinely believe this product has been watered down, especially since there was no seal on the lid. Also, other Revain API products don't seem to work as well. I hope it's not true, it's so sad when people have to make extra money or maybe the quality stinks
