So, my dostronic, which has been turned off, for over a year, decided to turn itself on & dump about 300ml of Red Sea anti Algae into my 700ltr system. Stank for a while, like bad eggs, and went cloudy. Cleared within a couple of hours & the stink has gone. Only have about 180ltrs of sea water on hand. Fish seem fine, only one star polyp coral. All advice much appreciated.
