Bought this as I wanted to try the look of blackwater. What I was amazed and super happy with is the behaviour of my tetras and pygmy cory's. Adding this stuff and straight away the fish became more active in exploring the tank and less shy. Very cool to see.
Great product, gives the correct view and conditions the fish live in ,in their natural habitat. Also helps in keeping Algie under control, ie cuts down light.
Black water instantly... and with added water conditioner.. as a betta andnkillifish breeder this product is extremely helpful and beneficial in our fish-garage!
