vortech is way way to pricey for me. the problem at the moment is finding out if the tank is tempered or not. i think im just going to have to go with a hang on overflow ( certainly not what i wanted ) and i can still run a closed loop without bulkeads.. i have seen some preety good setups with pipes over the back ( down one corner for the outlet ) and then over the top and around to top.. or wherever u want for the return. but im not to sure how to do the return at the mo. you see so many ppl with different designs... pipes in/under the rocks.. facing to all corners/front/sides/back. im not sure. think im going to have to play around with a few ideas that i have and see what happens
