Was at work when PB started pool.
Looking at your signature showing a build start of May 2016, I'm assuming the pool was just filled with water within the past day or so and that it is plaster-based (i.e., not vinyl or fiberglass). My response is based on these assumptions.
There is a special start-up procedure that needs to be followed to ensure the plaster-based surface cures properly. The builder should have gone over this with you. If not, and ask them what they recommend. They presumably have some kind of warranty and you don't want to do anything that might void the warranty. If they tell you to do something, you generally should, regardless of what we say, otherwise you risk voiding the warranty. To help you frame up the questions you may want to ask them, I suggest reviewing this article:
Start-up New Plaster
As for the testing, I would definitely trust the K-2006C over the test strips. As a resource, we have available these
Extended Test Kit Directions.
The POOLIFE TurboShock is a calcium hypochlorite form of chlorine (78% strength). It adds calcium, which plaster-based pools need to a certain extent, but it does not add any CYA. If 4 bags of this product were added (assuming 4 one-pound bags), it should have raised FC by 15-16 ppm. In addition, the 2 trichlor tabs would add another ~ 5-6 ppm (along with ~ 4 ppm CYA). If this was done this morning, you should have more than 0 FC by this afternoon/evening. Furthermore, the CYA should be nowhere near 90 ppm given the two products that you know the PB added. If you have a lot of plaster dust, it may be obscuring the dot and causing the CYA to read high. The only way that CYA is introduced to the pool is by adding stabilized chlorine (trichlor pucks or dichlor) or a stand-alone stabilizer product (CYA). It may be worth asking the PB to disclose all of the chemicals that were added.
If he left you any of the trichlor tabs that you described, I would not use any more - not because of the CYA - but because they contain copper. Adding metals to your pool will result in your having to deal with another problem.

PB stated I could go swimming today.
I would rethink that. Check out the Start-up New Plaster article I referenced above for some reasons why.
