I picked up this one at my local hardware store. You can probably find them for less cost on Amazon and other places.Any recommendations on purchase vs rent for a sub pump? Models you recommend?
Ah interesting. Yes- the water definitely turned purple prior to going to blue. I probably added 5-7 more drops until the purple turned to more of a blue. I will try again with 5 drops R-0012 before adding anything else. I will order the SpeedStir today.
Yes 10 ml water sample. I will try again with Speedstir. Any concerns on high pH on the fill water?When you get your Speedstir, once you reach about 12 to 15 total drops of R0012, start 'bumping', or turning on and off, the Speedstir between drops. Also wait several seconds between drops. The color change can take time to develop.
I assume you used a 10 ml water sample and each drop to blue is 25 ppm CH.
Thanks! Speedstir arrives Friday. I am out of town Saturday so not sure when I will get to start draining/filling poolThe pH of Colorado River water is typically 8 or just above. So that is correct.
I would think your fill water is closer to 250 ppm CH, 130 ppm TA. That is what ours is and we live 1/4 mile from the Colorado River and that is what is delivered to our home.
Mmmmmm.... great information to have for sure. I would also like to know where to rent/purchase a sub pump as well for future reference.If you place a low volume sub pump in the deep end and pull water from there while adding water in the shallow end (through a skimmer or into a bucket on a step so you lessen the water disturbance) you can do a fairly efficient exchange. That is assuming the water you are filling with is the same temperature or warmer than your pool water. If your fill water is much cooler than your pool water, then switch it. Add the water to the deep end (hose on bottom) and pull water from the top step.
Yes. It is a slow process. If you want a quick one, rent a 2 hp sump pump from Home Depot. It will pump about 3-4000 gph. You will need to go to your street with it as your sewer cleanout will not take that rate. You will also be draining your pool. Keep the plaster wet as well as you can. Then put your hose in the pool and fill it. It will take about the same 40 hours or so.So if I am filling/draining at 7gpm (420 gph), it's going to take 42 hours to turn over my 17,820 gal pool?
I think I'll just go the slow rate, have the flows matched and sewer clean out can handle the exit flow. We aren't supposed to run pool water in the street in Scottsdale according to the city website. Thanks for the info!Yes. It is a slow process.
