Hey guys, I have a sumpless 75 gallon up and running. I'm using a Tunze 9012 DC skimmer and a fluval FX4 for filtration. I'm starting to make some upgrades that I can transfer over to a bigger tank if I ever bite the bullet and upgrade. One of them I was considering was getting a reactor from BRS with that syncra pump. My question would be-- is there a drawback to running the pump on the exterior of the tank to save space in the display?
