I throw one in my tank every now and then. My shrimps seem happy with it. I like that it's simple
I've used one of these in two tanks now. They dissolved and rose the hardness steadily without raising ph. Especially important for me is that these dissolved in very high ph water, which crushed coral has not been having much of an impact on.
I just started using this product and so far it works great! Loved receiving all of my products and they even came with a cute fish sticker! My other purchase was easy green fertilizer and my plants are looking so much happier! Thank you for the products!
