The only difference is that i subdivided(simple subdiv not Catmull-Clark) the mesh 3-4 more times.
As you see the difference in caustics is HUGE.The first image is made using Photonmapping with Yafaray (real quick and low quality) Just for reference. Also i used Catmull-Clark sudiv for the Yafaray reference so its just a little different.

I used the sculpt brush not a noise texture for displacement. But this is irrelevant the key is that the tessellation is 3-4x degrees higher. I did not save the scene...i would post it otherwise but i can recreate it for you. The caustics are working more than nice but in such a close space when light sources can be located easily. Im currently trying larger scale pools not a tiny box. No luck so far though

Just a heads up that is possible and available with other renders -> Unbiased sun-pool caustics.
