here in Florida, we use safety fences which can be removed. the thin posts are inserted in small permanently drilled holes in the pool decking (concrete or tiles). the mesh is like a screen, and pretty much disappears from view. the holes are covered by small caps when the fence is not used. check with your local building department for their requirements on height.

Check out the safety standards published by ASTM for pool fences, pool covers and other devices intended to protect young children from drowning. Here in California, building and safety codes allowed us to protect our family with a walk-on pool cover and avoid fencing (which IMO is an unsightly alternative). Be sure to check out your local and county building/safety codes as well.
