Trying again to upload the design

I was under the impression that Diamond Quartz was just the premixed product that the applicator mixes with Portland Cement to form Diamondbrite.

We are going through the same process in Fort Worth, and have narrowed down to Diamondbrite or possibly Quartzscapes. Pebble Sheen and Pebble-Tec (and Stonescapes Mini-Pebble) were beautiful, but just a bit too rough for our little ones' feet (and swimsuits) in our opinion. Plaster is nice, but we'd like something a little sturdier after formerly owning a white plaster-finished pool. We ARE leaning toward Diamondbrite over Quartzscapes because of: 1) the premixing quality control issue you speak of; 2) the feel of the samples (Quartzscapes is a little rougher, though not bad); 3) our Pool Builder is ambivalent, but says his applicator has had good results with Diamondbrite and he is coming around on the product; 4) the color selection is more suited to what we're looking for (grey-green) than Quartzscapes - at least in the samples we got; 5) we've seen and felt Diamondbrite in a pool and the owner has nothing but positives to say about it; and 6) I've seen a few negative reviews here or at Trouble Free Pools (can't remember which) about problems with Quartzscapes blotching or not looking like the samples, which scares me even though I have a TON of confidence in our PB. Hope some of that helps.

As for the light, from what I've read elsewhere, I'd guess 1 light should be enough to light a pool of that size, though it depends on what look you're going for. For instance, I expect some shadowy areas and attenuation at the edges of the pool at night, and even prefer it.

I have used both Quartzscapes and Diamond Brite when building pools. The difference is that Diamond Brite is premixed, so it is a more uniform finish. It is not hard on the feet. Quartzscapes saves a lot of money, but the mixture is done onsite. You will see more variations and shading and mottling with Quartzscapes.
