You might want to check out LaveyCraft. They build a superior product thats quality is second to none. I would suggest either the 24NuEra, 26NuEra, or the 2750NuEra for you. They run a twin stepped bottom that is fast and efficient for all water types. Check out there website and give them a call, most down to earth builders in this market, and a family business.
