Hello, I read that the water height is about 36 inches on the 42 inch Intex Ultra. Does anyone know if one would be able to not fill it up all the way? My daughter is not quite tall enough yet for that. I wanted to see how much wiggle room there is with the water height (i'm thinking the inlet level would be the limitation right?). I'd rather not buy a whole new pool next year just for a few inches. Thanks!
