Hi there! I have some problems with Dino, probably Ostreo. Today I have decided to suck out all od the Dino from the sand (a lot of). After that, most of my fishes started to heavy breathing. Almost 1h after the cleaning Chromis Viridis was dead, few ours later Ecsenius Bicolor was also dead. Is it possible that Dino released toxic into the water and it is killing my fishes?
