I have a new 210 Gallon build that I am working on. I have used both Vortech and Tunze Pumps in the past and I am leaning toward the Tunze for this tank. My problem is one end of the tank has a cabinet build so I don't have room or access for the magnet on the outside of the tank and I can't get to the back. However in a previous post it was recommended that the 3000.250 rail option could be used in a circumstance like this. My tank is a standard All-Glass with the top rim/lip. Will the 3000.250 work with this rim design? If so I will be ordering a new set of 6205 pumps to use in this tank plus the rail kit.
