What type of supplies do you keep on hand in case of a tank emergency? I have an extra powerhead and an extra heater. I am asking this question because my pump to my 55 gallon just burned out (salt water dripped on it until it quit). I cannot remove the pump (the sump was built into the cabinet and I cannot unscrew the pump from the sump...). So I am currently running my skimmer and a powerhead in the main tank so that the corals and fish don't die until I can upgrade.
