Hi all, big emergency here! I came back and all the fish were at the bottom, breathing very slowly, I managed to get the power back on as the outlets the fish stuff was plugged into must've short circuited or something and now they're back up and swimming around though my fantail is flashing it seems.... She will occasionally get these spasms where she swims to the very top of the tank and then back down extremely quickly. I don't have a functioning Ammonia reagent as it is giving me invalid results so I'm curious, should I dose Amquel+ to keep them safe from Ammonia, Nitrite and Nitrate poisoning? I don't know how much to give them and I'm also not sure if the bacteria is dead or not. Please help. How much amquel+ should I dose the tank since I can't do a WC right now?
