It is now running in pool mode. I think it was the weir door. I didn't even think about it but it came loose and floated into the skimmer basket. However did that just happen but was not problem to begin with?? As I said the PB tech had it running--appeared to be in pool mode--water coming out...

I've attached a picture of my system. I want to understand how it works. I'm somewhat technical and should be able to catch on. I'm having some problems and want to understand what my PB is doing and why. We just replastered and he started it back up this week. It was running in service mode...

Problem solved! The plasterer did not do the acid wash after spot test proved not to work. They are re-plastering. He said he believes abalone added to the plaster mix (a small upgrade we paid for to add a little sparkle to the plaster) is the culprit--says he's only seen it a few times but if...

Thanks again for all the support and information! When you say, "brown stains are actually calcium scale with dirt embedded in it", is that referring to the problem caused from adding too much calcium chloride to the plaster mix or is that something else.

I wonder too!! Because that is something the first guy he sent out tried so obviously he knows that didn't work. He said if the acid wash didn't work they will replaster and I can only hope he means it. They are draining and doing the acid wash Thursday and told me replaster is scheduled for...

Forgot to add, that chlorine is added via inline chlorinator. Highest chlorine result has been 5ppm and only occurred a couple of times in winter. Definitely didn't have that happening in our warm summer time.

Thanks for the reply! They are planning to drain and do the acid wash soon. Regarding the spot test, do you mean try it on a small area of the discoloration to see if it removes it before washing the whole surface? I guess if it is going to remove it, they will know immediately? Do you have any...

I have a pool plaster problem. There are greyish/brownish mottled areas--your posting that talked about "hydration" problems sound similar but I'm not sure . I've uploaded a picture and hope for some opinions on what my problem is. I have 20,000 gal chlorine pool with pebble tec that is 10...
