Review on Seachem 116038706 Safe 1 Kilo by Brittany Smith

The price of this product has increased by over 40% in the last few months. Not the same offer as before. Maybe now it's better to look for another option. Works pretty well, but don't trust the instructions. You need a highly sensitive chlorine test kit to see how much chlorine is left, especially when breaking down chloramine. It may take several full doses per day to actually neutralize the chloramine. Aquarium chlorine test kits are useless, much smaller amounts than they can test will kill your fish. It has cost thousands of dollars in dead carp to finally verify everything.
