Alright it's that time of year again. My Tom's Aqualifter has started to run into problems maintaining the siphon on my Overflow Box. however, I've run into a new problem (new for me at least). It looks like Tom's Aqualifter pumps are discontinued and I need an alternative that is okay to use continuously. I've noticed that in the description of the Avast Marine and BRS Pumps that they aren't supposed to be used continuously which is a bummer. Anyone have any recommendations?
