I have a new Fluval Flex 15 gallon tank, which had a fancy remote for the lighting. The remote has a button that puts the light into a storm mode, wherein it flashes like lightning -- a spectacular effect, but not one that I want to use on a day-to-day basis. So, I chose to have it operate in the normal daytime mode. It works great. Except... I plugged the light into a timer which turns the power off at night and back on in the morning. When the timer switches the lights on in the morning, the light spontaneously goes into storm mode. I then have to get out the remote and turn off the storm effect. This happens anytime I remove the power from the light and power it up again-- by unplugging the light, via the timer, or via the power strip that supplies the entire system. I called Fluval and the support person said that my timer is at fault. Can anyone with such a system on a timer let me know what sort of timer you use? It's an irritating problem that I'd like to fix.
