ok, the tunze are very good powerheads, likely the best you can get, and you will pay for them. i dont know what overflow box that is but they are all pretty much the same. all that matters is the diameter of the drain hole. 1" is rated to flow 600 GPH down, so if that is all you have that is the max you will be able to push back up. if you go over that your sump runs the risk of running dry cause the pump is pushing too much. a ball valve on the pump can be used to 'throttle it back'. also find out on the sequence website what the Tarpon pushes at the head-height. that is how high up from the pump is the end of the return line postioned? 4 ft? 5 ft? the website will tell you what your actual GPHs will be like. so depending on what you have for your pump circulation, you may want to employ 2 over flow boxes, or one that is of a larger diameter than the standard 1". the majority of your flow however should be from another source. Tunze are good because the engine is mounted on the outiside of the tank and megnetically push the blade on the inside. to me , it is still clunky over all but at least you are saving yourself extra heat sinks. Heavily consider CLS - closed loop system, for the bulk of your flow. easily installed with a little PVC and a large pump. this will remove PHs from the equation, freeing up tank space, not transferring heat, providing a LOT more flow, and saving you money down the line as PHs do NOT last forever. oh and with skimmers always go with larger
