we have done the muriatic acid test and used wet/dry sandpaper (1000 gr) as instructed by out pool manufacturer and when sanded the color is under the shadow/scale substance! we are getting ready to have ecofinish (polyfibro) done to pool! Has anyone on this site familiar with this process?

Welcome to TFP.

Use SEARCH on the top of the page for “ecofinish” and you will find a bunch of threads on it.

@Texas Splash may have thoughts on your scale problem.

Welcome! :wave: I have not personally had the ecofinish done, but you might look at the following thread. A couple of those members have had it done with what seems to be mixed results.
