I used PVC in the ground but EMT on the cage itself, above ground. It just looks better and doesn't sag.
Some of the bending was tricky but that is half the fun
The other thing was I shot it all with medium bronze paint after it was bent but before I put it up, for additional corrosion protection and so it blends with the cage material. I was very happy with the way it came out. I have 15 H-101 style lamp holders around the pool with 15w sign bulbs in them. It makes a real nice light level without that "stallag 17" look. There are also 2 underwater lights on dimmers. I also have some PAR 38s on a separate circuit for when the kids are here and we want it bright.
