I’m going to be going on vacation next month and we’ll be gone for about seven days. I realize I can get a timer that will go on and off, but I have a Fluval flex all in one tank and after the lighting is turned off, you have to press a button on the remote to turn on the lights. So a timer really wouldn’t turn my lights back on. Will seven days in the dark be too long? What kind of problems could that cause?
