WOW! That is fabulous!
OK PoolDoc, this may be a first for you.
Let me start with some disclaimers, this was only the second time I have flown this drone and I had only 15 minutes of stick time. It was windy. No one was hurt as a result of this production. The video ends rather abruptly, the drone is fine but alas, the Gopro was not so lucky. I think it was wind shear!! Another Gopro is on the way. Enjoy!!! Oh yea, the resolution was not set correctly

Some pool!
One more video with the new GoPro

Cool pool, and interesting video . . . but I'm not going to get in a plane you're flying, until you've had a bit more practice! ;)
Either that or he trained at "Top Gun"--in which case I am not flying with him! (where's the "chicken" smilie?)Quote:

My back yard was in the middle of the southern leg of the Thunderbirds performance loop. They'd always run practice flights the day before, getting low enough so that once one of my sons got a wave from a pilot!Quote:

A chance to do so, would be the ONLY reason I'd voluntarily go to Six Flags or somewhere similar -- so I could 'flight train' my stomach before getting strapped into the real thing.
Thanks guys. You can see the way the palms were blowing that the wind was pretty intense. On a side note, when I was younger, I did solo on a Cessna 172. Take care.
OK. I'll buy that.
Some years ago, I did some consulting and design work on a community condo pool at a luxury resort, and had to commute private plane, in a 1 1/2 hour flight. Several times, I was in a twin engine Beech, but mostly a single engine 4-seat Cessna, which may well have been a 172. On one return flight to Chattanooga, my pilot was threading his way along the NC/GA line between thunderstorms that were both south and north of us. I got into the co-pilot's seat with a fresh cup of coffee, before the pilot noticed. Once he did, he warned me to drink as much as possible before we got above 300 feet. I got a few sips before I had to cover it up with my hand. When we entered the downdraft across the primary mountain ridge, he was in a maximum throttle climb, and still losing 100 fps.
Needless to say, I didn't get another sip of coffee, till we landed in Chattanooga!
Have fun! I LOVE to watch them fly! As long as MY feet are firmly on the ground!:DQuote:

I'm getting feedback from various sources that pools with infinity edge often began to have problems after a year or so, and end up been run with levels below the water flow.
I can think of several ways to run a pit below pool level, but some are much more reliable than others.
There are 3 drains in the catch basin and 6 returns at the shallow end of the pool. It has a Pentair variable speed pump that only controls the flow of water over the infinity edge. It's the 3" line on the left of the picture
http://i814.photobucket.com/albums/z...ps9d8c952d.jpg
Ultimately when all the wiring and controls are done the pump for the infinity edge will start when any of the water features that put water into the pool or basin are turned on. The water bowls, the exterior mini waterfalls on the side of the raised beam or the herons
One thing you'll need to watch for: any time the edge is ON, you'll be stripping carbonate alkalinity and raising the pH. The process won't stop till the pH is around 8.0. It will take time to learn how to manage it, to maintain carbonate saturation. But, given all the tile grout and plaster you have, it will be critical.
How were you planning to treat the pool? There's something feeder-looking between the filter and the Pentair pump. What is that?
What's the Pentair driving? An infloor cleaning system?
The other Pentair pump is running a few of the water features as well as an in-floor cleaning system. The 3rd pump will be running the bowels. We will be using Tri-Cor tablets for chlorination. With the aeration that we are doing it should help with the CYA. I understand as you have pointed out, that with the water flow into the catch basin that it will have an impact on the PH. I am having an outside service take care of the pool but I also have a test kit of my own to keep another set of eyes on the readings. Thanks for your continued comments and advice.
Ok, thanks for the info. One more question: in looking through the photos of the pool, I noticed a number of outlets on the wall of the pool closest to the house. What are those?
And . . .
Huh?Quote:

Sorry bowls not bowels. With the water falls and mist and evaporation that goes along with it, the need for replacement water increases. Replacing the water at a higher rate in effect acts as a counter balance to higher CYA. This just means I will go a longer period of time before I will have to drain and refill the pool to lower the CYA created by using chlorine pucks in the chlorinator.
The outlets at the end of the pool are the returns for the catch basin and the other are the returns from the skimmers
Thanks for the info. I think I can visualize the system functionally, now.
Actually, that's not correct. Losing water to evaporation has no effect on the total quantity (mass) of CYA present in the pool water, just as solar evaporation does not lower the ocean's salinity. The reason is that the water vapor -- evaporated water -- is essentially distilled water, free of all chemicals. Some volatiles may be present, but CYA does not have a significant volatile fraction.Quote:

3. Biodegrade with heterogeneous 'slime' composed of algae and soil bacteria. This happens naturally, but is unpredictable as to rate of degradation (2 weeks to months) and endpoint (nitrogen gas, nitrates, or ammonia).
To be clear, I am not talking about evaporation by itself. I am talking about the mist created from the waterfall's (I have three) over the infinity wall and the other two mini falls as well as the mist and water disbursement because as the water falls the wind carries some of it away. If you have ever been to Niagara Falls that mist that is in the air is a direct result from the falls. This necessitates the need for more water. In effect I am replacing more water than a standard pool. It will not completely remove the appropriate CYA, but will delay the need for water replacement on a wholesale basis
More work going on. We still have about 6 more weeks of work

OK, you are correct -- water leaving the pool as mist would take the CYA with it. I hadn't considered that.
It’s something I will have to measure over time and see what the data looks like
It will be interesting to see the results -- in several areas.
I'd love to see actual timed measurements on pH & TA over, say, a 12 hour cycle of running the overflow.
The work continues. The PB worked on programming the lights on the pool but still has to work on the remote. The PB is working on the quote for the landscape lighting. I took a few pictures tonight.

Looks cool!
I know I sound like a broken record, but the work continues. We are in our 10th month of construction and am getting close to the finish line( relativity speaking). We have had outside furniture In storage for 5 months. The statues below are ones I found at a gallery when I was in NYC. They are carved out of a single piece of Carrera marble

Your water looks beautiful. I assume you have gone swimming by now. ??
Hmmm, New York, Lions. Did you buy them in front of the Library?
Thanks for sharing your project here. I enjoy watching the progress. Looks great.
Yes, we have been in a number of times. it's great! The PB figured he needed to get us into the pool as he continues to work. We had the heat cranked up to 90F but cut it ba.ck to 86FQuote:
