I've got two girls ages 7+9, and space for at least a 15' maybe 18' pool. 36-48" but no more. Youngest daughter is not quite 48". I've got big shoulders so excavating dirt is no problemo! But thinking seasonal even tho we live in Fl. That way I don't have to worry about cleaning all thru the year...3/4 acre lot with 23 pines all 50' + in height. I'm a aquarium enthusiast, SW and fw, so testing and quality control are no big deal. I'm used to maintaining tanks of water, this pool should just be another "tank" just with different parameters and chemicals. I've read thru pool school and the temporary pool sections. Budget is 300 or so. It's getting hotter, and these kids are constantly bugging me to take them to the beach. We live 15 minutes from the "Emerald Coast" and the worlds most beautiful beaches. Never had a pool before, but love the idea of the tfp method. I'm open to suggestions!!!
