Excellent Value
I have a 20 gallon fish tank and this is a necessity to keeping the fish healthy. This is a better value to purchase in a larger quantity than the smaller 10 ounce bottles. For the size of my tank this large bottle makes it hard to measure and pour the correct amount so I did keep a smaller bottle that I had previously to refill from this one. It has kept my fish healthy and would recommend this product for your tank.
