Yes, it's right at the water line. Will have to get an acid brush...this is the first I've heard of one. I'll get a squirt bottle and mix the acid 3:1 to see if we can get it off. Our softener isn't tied into the outside water spigots and we have pretty hard water here.

Is this white spot scale? We have a spot like that on every grout line between each tile. Gentle scrubbing with the nylon or wire brushes doesn't help.

Thanks :) We added a pound of CYA and will monitor to get it to 70 ppm, as well as checking the FC level to determine when to turn the SWCG back on. Appreciate the guidance; we've learned a lot through this process the help here.

The range for calcium is 350 - 450; ours is 550, so I thought it needed to come down? Shouldn't all the numbers be in the ideal ranges? Or is the CSI number more important than the individual ranges? Super helpful tip, thank you!

Also, the SWCG has been off since we began the SLAM; we should leave it off until we get the FC level within range, correct?

So we shouldn't worry about the CH or Salt not being in the target range for now?

FC 11.8 pH 7.8 TA 50 CH 550 CYA 50 Salt 3000 Borates 20

Okay, test results are entered and saved. I did not see a place to save the Borates in the CSI table, but that is about 20 right now. Edit: Found the place to turn on Borate tracking.

We only tested the FC, CC and CYA this morning; I think I'd read the pH testing wasn't reliable with the high levels of chlorine during SLAM. We'll go ahead and test the rest. I don't see a save button on the PoolMath page....am I overlooking it?

We completed our SLAM and passed the OCLT this morning. Water is clear and CC was about 0.3. The article on SLAMing says to let the FC drift back down but I was wondering if we should do anything with other chemical levels at this point. Should we use Pool Math and follow the guidance from...

Tonight the pH is back up to 8; TA is at 90. I don't understand why are we having such a hard time bringing the pH down?

@IceShadow, thank you. TA is still 110--math says to add 27 oz, so we'll do that and test pH again tomorrow. @frogabog roger that and thanks. i've done a lot of reading in the last few days, must have mixed up a couple articles. appreciate the feedback :)

@duraleigh it came down to 7.8.

It was a typo, sorry still getting used to the abbreviations. We added 5 cups of muriatic acid yesterday and wondering if we should add the same today since the PH is still not down to 7.2.
