I have had a fish tank for a long time and running a pump 24/7 is what the pump is designed to do.
BUT for a computer running your pump 24/7 you create more RISK. I have a Eheim 1048 now it does not get that hot but if the computer is Not on the little heat from the pump will build up in the case b/c of no air movement, so when you start your system your starting out Warmer than usual, including water in Rad.
PLUS if running pump 24/7 there is more chance of having a water leak, burning pump up, ruining hardware, etc.

NOW having pump on a Relay you just keep hitting the pump with voltage every time you turn it off or on. Pump really not designed for that, could cause it to get noisy over time or burn up.

These are all the Negitives I can think of. What do you Do or Suggest?

Thanks
