Help with cracks and spots

[mterrell77]

So my pool was finished first week of September. I followed everything on starting a new plaster/gunnite pool.
This week what I thought was algae I realized is actually reddish/brown spots. It started with one now there is five. I have tried and tried to brush and nothing happens. While doing this I noticed two large cracks in the pool plaster. One on the side of the pool and the other at the bottom of the pool.

What should I do about the cracks and the spots?

M,

What has your pool builder or the Plaster guy have to say?

In my case, I had a couple of minor defects that they went in fixed underwater. looks good and you can't tell anything was done.

Was this new construction or a re-plaster of an existing pool? I would have the builder or plaster contractor (if it was a re-plaster) come take a look and see if they will repair this under warranty. I can't really see the red spots but that may be rust stains where rebar touches the plaster.

This is new construction. I have him coming to check it out. If the stains are rust stains what can be done about that?

Please post more pictures. That does not look right. Pictures of what pool looked like before plaster and pictures of cracks.


Also a complete set of test results

Ouch - Looks like its delamination - Marble or quartz based plaster?
