My pool is going to be 33 ft by 19 ft. I will have a spa, grotto waterfall, and some weeping rock falls. My question is this. Do I need a separate booster pump for the spa/grotto and weeping rocks? If I don't get one and have a VS pump what would the drawbacks be? I'm assuming that when I am in pool mode all the spa spillover, grotto and weeping rocks would be flowing? (how much pressure would i have)? When I am in spa mode does that mean, I wouldn't have any water flowing for the grotto or weeping rocks?
If you do recommend another pump is the 1.5 HP the right one or should I get a different HP?
