In this case, I believe you need PGI cache, as the caustics viewed from outside the water will be SDS paths. BiDir would help if the camera is inside the water.

I need help to create a good water material for the pool; now is a simple plane with glass material IOR 1,333.I should to add interior or exterior volume? There is a lux tutorial? Here references https://www.archdaily.com/907558/gg-house-sommet

CoolColJ shared nice water material, it's still up in Indigo material database.
If my conversion is right from absorption to transmission (if transmission is color at depth).

Absorption:
Depth 1m
R 0.966298
G 0.985604
B 0.981817

Scattering:
R 0.985789
G 0.986962
B 0.98815
Scale 0.010038

From the data in refractiveindex.info webpage i calculate the
ior 1.3262
Dispersion 0.002152

Do not use multiscattering, it's too slow

I wonder where is the weird green/yellowish colorcast from sunlight coming.

I find luxcore sun incredible difficult to control especially without proper white balance controls in camera. The moment it goes closer to sunset/sunrise, the whole sun&sky system becomes pain. We need the ability to directly control sun color and in camera WB controls too.

Just use gain color :idea:

even desaturated sun color and even disconnected from sky model it will still turn weird yelowish cast when nearing sunset/rise angles. The only way around it is using direct light.

I've wrote a very very naive white balance plugin a while ago. I will clean it up, rebase and make a pull request so you can test it to see if that helps.

White balance in Photographer (addon) works nice with Lux.

I end up with this with the same HDRI : (Only gain color correction)
