Combining three tanks and sumps to one giant system and sump

Anyone have advice on completing this in expensively? I have a friend who will help plumb, I have two 180 and a 125 the 180 is upstairs the other two in basement where fish room would be. I would like a giant 150-200 gallon sump for combining scrubbers and skimmers where I can dose all three tanks.



Anyone done this? Any advice? I want a large macro algae section in it as well. Rubber made tub work?



Lost!
