You have to remove the light and loosen the Clamp to rotate the lens. I've done this a few different times in different pools and never noticed a difference. It's definitely not worth messing with in my opinion

All that steam you saw leaving the pool wasn't Christmas spirit... that's a huge temperature difference and I'm surprised you didn't lose more water.

What are you looking to achieve?

Acid has a ludicrous amount of chloride in it and I imagine you're going through a lot of acid. Almost every chemical you add to you pool has some sort of salt in it.

That's probably the simplest way and pretty reliable too.

Your pool and its occupants will thank you for it! Please don't forget to post a picture of your Halloween costume

Pool Math uses temperature...why do you say it doesn't? Pool Math uses total alkalinity and provides several adjustments (bicarbonate alkalinity and cyanurate alkalinity) that make the CSI much more accurate than the spinning Taylor wheel of death. CSI is determined from pH, TA, CH, CYA, water...

Just like that super smart and really good looking guy said a little earlier?

The heater is fine, it's low pH that causes damage. Your FC level should drop soon enough

The water temperature is what's causing the low number... Not much you can do about that. Your CSI isn't cause for concern right now. Keep it up :goodjob:

Plaster The grout is cementitious and will greatly benefit from the same water parameters as a traditional plaster pool.

There have been hundreds of sensor failures this year. Give Pentair a call and it will be covered under warranty. It only takes a couple minutes to install and it's easy to do

Your math is correct and you are at a big disadvantage since the surface area is so large compared to your volume because the shallow depth. I see a pool cover in your future...

There are millions of people with pools that have no idea what CSI is and keep their water extremely negative unknowingly for years on end. The same people are getting multiple decades out of their pool plaster so with you keeping an eye on yours I don't see why you should experience any...

I highly doubt those defects are a result of anything you did. Your water was aggressive but not quite as bad as what most do in a traditional startup. What is the builder saying?

The vitamin C should do it then

That should do the trick if the stains are from an external source. If they are stains from the structural rebar rusting, then that's going to be another story.

Your fill water is very high in calcium so every time you top off the pool you are adding more calcium. These late summer/early fall months are notorious for being both windy and very dry which drastically speeds evaporation. There isn't much you can do unless you add a water softener to your...

You can follow the TFP recommendations without worry.

If you still have tile and grout in the pool then I suggest you follow the recommended levels for plaster. You don't need to give the calcium level quite the attention that you would in a plaster pool but it is still important.

The TA test is being thrown off because of how high your chlorine level is. The test is still valid but the color change will be different. Try adding 10 drops of R-0007 and then add the R-0008. Why is your FC so high?

We can use it as a target for the guests to aim at when they drain their bladders. That might actually get them out of the pool...

ITS ABOUT TIME!!!!!! You'll be invited to the season closer! You've been added to the guest list!

You won't get an invite until you name your circuits in ScreenLogic :hammer: - - - Updated - - - I'm pretty sure I fired down 3x my allotment of beers :cheers: There were probably 20 something kids here and most of the women were were doing mixed drinks so probably more like 300/30= 10...

It was Moana... What else!? I use a projector and bought some projector screen material off Amazon. My mom was nice enough to sew it and put some grommets in it to mount it to that pergola of death. Same at my place. I've got it memorized :crazy: So then there would be pee and poo in the...

Next party!

We threw a pool party yesterday and had about 60 people in the pool. By the day's end the water was so murky that you couldn't see the drain covers through 6' of water. Now 24 hours later the water looks as good as it did before the party. I took the FC to 12 (my CYA is 90) and and lowered the...

Baking soda does nothing to keep pool water clear. What you are seeing is purely marketing hype. Clear water comes from adequate chlorine levels and filtering... nothing more.

Jaime, I kind of think you are micromanaging your water chemistry somewhat. Remember etching the surface is not something that happens quickly and would need you to have a CSI below -1.0 for a very long time for it. I know you said you have some etching but I highly doubt it was from you. I bet...

The yellowish areas, are they raised and rough? It kind of looks like scale and with your CH level it is certainly very likely.
