new 54 gallon reef ready aquarium

[reefer1121]

hey all,

i just purchased a used 54 gallon corner aquarium and Amiracle wet/dry filter. i have a question regarding flood prevention. in the case of a power outage, how do i prevent water overflowing into the sump from the main tank? the back wall cover has openings on the top and bottom so i am concerned that if the power goes out, water will continue flow out of the main tank until the water level reaches the bottom openings. thanks for your help!!

extend a pipe up from the bottom hole to the same level as the top hole (middle or lower half of the top hole)....That way the water will stop draining

ps- make sure to use a bulkhead in the bottom hole

thanks for the reply. what holes are you talking about exactly?

another question, how exactly should i go about my water changes? do i simply just turn off the sump pump, syphon then add new water, then turn it back on? i want to make sure i get this right before i have some sort of disastrous flood
