Hi all,

New build in final stages, water in pool since Jan 27.

Waterfall from SPA - water constantly hits rock edge, will this create any long-term problems? Pic attached

PH tests coming back high and adding acid as tests call for. Normal to be high with a new build?

I've also just updated signature, any recommendation or formattingwaterfall.jpg
suggestions?
 
Congrats JW! Looks nice.

Yes. Keep acid handy and test often as the new plaster will take a while to cure - perhaps a few months really. As for the spillover, besides adding to your pH rise (aeration), I can't think of much other than the residual splashout and perhaps calcium staining that might need some cleaning from time to time. When not is use or really required, I'd try to reduce that spillover time to cut-down on the pH increase. Run it only for ambience when you're actually out there or during spa water turn-over. Hope that helps.
 
Your pH will rise not only due to the new plaster but that amount of aeration long term is going to be problematic. I would suggest adjusting that soon to just running once a day for 30 minutes or so. Your Automation should be able to achieve that.

The water impacting natural stone will erode it over time. Also, if you have hard water, you will have significant calcium deposit build up on the stone in that area.

Take care.
 
Thanks guys. Didn't realize aeration would increase PH - good to know. Same for sheer descents? We have 2 18 inch

The automation hasn't been fully programmed, should have that done soon (I hope). I think SPA mode is where there is no spillover.
 
SPA mode will only be used when you wish to use the SPA. You need to have a POOL mode that is Pool only. No Spa or spillover. Then a Spillover mode that puts a bit of the return water into the Spa but the suction is from the Pool. That will let you clean/sanitize the water in the spa each day.

Any splashing/aeration of water will increase your pH. Waterfalls, spillovers, sheer descents, etc. You will only want to run them a short time each day to keep the water in them clean and then when you want the ambiance.

If you force your pH up every day with aeration, you will then need to add acid very often to drop the pH, which will lower your TA. Then you will need to add baking soda to increase your TA and the merry-go-round begins!!

Take care.
 
JW,

On the bottom side of the that rock overflow there should be a 1/4" wide and 1/4" deep slot that runs across the whole overflow.. it should be about 1/4" back from the front.

This acts to break up the surface tension that makes the water wrap around the overflow and back into the rocks on the wall.

Increasing the overflow rate will also help move the water off the wall..

That said, I agree with the other posters that suggest you use this overflow as little as possible.. While these overflows and sheer docents look and sound cool, they can lead to other issues, so running them all the time is not a good idea..

Thanks,

Jim R.
 
jw,

Then your pool builder does not have a clue as to how things should work...

In the pool mode, water should be sucked from the pool, by your pump and then pushed through your filter and back to the pool. No water goes to the spa.

For water to go to the spa, while in the pool mode, ether a 'make-up' pipe is sending water to the spa or the return valve is not adjusted correctly. If you have a 'make-up' pipe, there should be a valve to shut it off.

Post a couple of pics of your equipment bad and we should be able to point you in the right direction..

Thanks,

Jim R.
 
Ours is setup the same way. In Pool mode the water is sucked from the pool but a little bit of that water is sent to the spa to keep the water in the Spa circulating. The spillover is on when in Pool mode, just to varying degrees depending on what our variable speed pump is set on. The spillover is not on when in Spa mode.

We had the same result when we bought this house. The reason in our case was that the previous owners had the return actuator set so that Pool Mode did not close off the spa return completely. It resulted in water returning to the spa and causing a permanent spillover in Pool Mode. pH rise was a problem, so I reset the cam in the actuator so that the spa return is completely closed off when in Pool Mode.

The other way we get spillover in Pool Mode is if our in-floor system is opened up. It rotates through a station in the spa and adds water to the spa that spills over.
 
Aqualink RS? Originally was supposed to be PDA but will now be app based.

With the Aqualink RS you can do full automation. I have no experience with it but others on the forum do.

Your PB does not understand automation. Have them install it and work with folks here on programming it.

Take care.
 
If you aren't going to press your PB to set the Spillover up, then you should confirm with him that the Aqualink board he installed has enough auxiliary positions to create a Spillover mode.

Aux #3 is dedicated to Spillover by Jandy once you flip the necessary dip switch, so you'd need to move any Aux he already plugged into #3 over to another, empty Aux.
