New Pool Plaster

Hello. We are getting close to completion on our new pool and the pool builder is planning on using Hydrazzo for the pool surface. I have several questions. 1. Any known problems with this product, things I should be aware of? 2. Info on the product states you should use a sequestering agent on start up and regularly thereafter? My last pool was maintained flawlessly with the advice from this forum and the Pool Solution kit. I used only liquid chlorine to maintain it. I don't like the idea of adding a sequestering agent just because, but thought maybe someone on the forum may have more info in this area. 3. Is the start up and maintenance the same with this type of pool surface versus a plaster pool? 4. We are having a AquaRite chlorine generator installed this time around, what considerations if any are there versus using just liquid chlorine? (Trying to figure out what, if any, differneces between the two in chemical maintenance.

Your input and help is appreciated in advance.

Thank you.
