I have a new installation with a spill over spa about 40-50 ft from the equipment pad. My spa has 2 in lines for suction and 2 for returns. I have a variable speed pump connected to my spa and pool with valves to direct the flow and same for a return. I have another dedicated pump for 4 laminar Jets. The spa has 25 Jets. The hookups on the spa are 2", reduced to my lines which are 1 1/2" I also have two 3' waterfalls connected to the main pump. My question is what kind of pump should I connect to the other 2 connections on spa? Should I use a regular 3/4 hp or higher pump? Should I use a booster pump? and if I use a booster pump what hp would give me the best jet action? I am a complete newbie when it comes to hooking this up. Thanks for any help it is much appreciated.
