Fish Fanatic
Just in case anyone here thinks to use this to give the fish all they need as per the leaflet. Be wary of using if the current inhabitants are used to current parameters. I tried some ESHA OPTIMA as i thought what harm could it do, plus i was aware my tap water missed some essential vitamins. Over the place of 2 days i lost 3 tetra. I can only conclude the change in parameters killed the fish. Just another learning curve - If it's not broke don't attempt to fix it
