We had a small problem with alge on our koi pond. The owner Rich sold us a solution to kill the alge. We followed the directions to the letter. Killed both our Koi which we had raised from babies and had for 2 years.\r
Other fish stores told us Never, Never, Never use the product expecially in the summer when oxygen is low. I would highly recommend avoiding this "fish expert" at all costs!!!!!!!!!!!!\r
