Hello Guys,

Im trying to make a render with clearbleu water. I use water type'water pool light' in sketchup with opacity of approx 60. But wen i use the podium browser material properties i get a verry glossy reflecting mirror type dark blue. I use the following values; D0 T62 R38 Refraction 1.33 and bump depth of 5 in the material browser. 
I want some azur blue pool with transparancy to see through the water.
Someone knows how to set this up?
In attach a pic of what i mean.

Thank you guys or girls

Welcome to the forum Gino!

If you want the color of the water to be visible you will need to have some diffuse.  Right now you settings only make the water reflect the environment at 62%. 
Set the right color you want for the water and play around with the diffuse setting.

P.S moved this from the Trick and and Category as it is meant for please to post tricks [smile]

You shouldn't need a reflection value of more than 10% for water or glass

You need to think about what you would see in reality. What is the colour of the surface below the water?

Clear water has no colour. If it looks blue, it is because of absorption and reflection of different wavelengths of light or it is reflecting the sky. See this https://en.m.wikipedia.org/wiki/Color_of_water

Critically, the colour of the surface below the water is one of the most important factors.

If the colour of the surface below the water is a dark colour (like in your image) the only way the water will appear blue, is if it reflects the sky. In reality we have something called the Fresnel effect, which changes the reflectivity depending on the angle from which the surface is viewed. Look at the surface from a steep angle (90 degrees) and it will look least reflective. As the angle reduces so the surface becomes closer to parallel to the direction of view, it looks more reflective.

You are looking at only a small part of what you want to achieve. If you think about swimming pools for example, they always have light coloured surfaces below there water.

So what are you trying to do? Do you have a picture showing the effect you want?

You know what affects the colour, if you want it more blue, change the colour of the surface under the water to blue.

I thought that was an updated image showing an updated render...

You need to post 2 things:

1. An image showing what you want to achieve. It looks like we have this.
2. An image showing the current results

Use the More Reply Options button at the bottom of the Reply panel, and use the Insert Photos option.

We can't help you very well if we can't see the results you are getting [smile]

I was playin around and made some pics of the water. But none of these pics are like i've wanted and like the picture i've sended. Nr 3 is the best because of the stairs i see under water, but the colour of nr 1 is better, so what do i do now? The colour of the water changed also even i didn't touched the colour. Under the water i have a white colour.

hopely someone knows what to do now?

Use the water from the Browser. Experiment with the colour of the surface under the water.

We can't comment unless we see the material settings for each image.

You only have 3 parameters, diffuse, transparency and reflection. Adjust them and the colour of the surface under the water until you get the result you want.

This isn't difficult, it's just a matter of experimenting. We have created lots of images with water over the years, it works just fine, you just need to play around for a while [smile]
