# Thread: Glitch in the Pool Calculator!

1. ## Glitch in the Pool Calculator!

HAHA-- Joke below.

So I need a target for the following.

100 Degree weather for over 5 days, and counting. Have not used any solar cover, nor heater (obviously) My pool is almost 90 degrees.
So with a 10,000 + gallon pool, how many bags of ICE do I need to add, to cool it off?

Hope you all are enjoying your crystal clear pools!

Cooling off,,need you a fountain or sprayer do get that pool water in the air.It will cool off some then

I dont know about bags of cubes, but I have been told to use about 10 blocks on my 20,000 gallon pool to drop it 5 degrees. I have never tried it, but have been told it works by folks in Arizona.

If you search here you'll find that answer

5. ## Re: Glitch in the Pool Calculator!

As a rough estimate, the pounds of ice required would be (V/1000) * DCD * 43.75

Where :

V = Volume of Pool
DCD = Degrees Cooling Desired

So..for your 10,000 gallon pool to be cooled 5 degrees:

10 * 5 * 43.75 = 2187.5 lbs of ice.

Good luck with that

how many recirculated gallons of water 8 degrees below pool temp?!?

7. ## Re: Glitch in the Pool Calculator!

6,250 gallons need to be cooled by 8 degrees to cool 10,000 gallons by 5 degrees, assuming no other factors affect the temperature in the meantime.

Use this calculator: http://www.onlineconversion.com/mixing_water.htm

It does mixing of ice, water and steam! Good luck!

Dang it sums gallons of water mixed! I want to take out water cool it dump it in via fountain, want to know what type of flow I need at x degree temp loss....

You all are so much fun here. I think I will just take my daily swims at dusk, and look forward to the 80's they are predicting next week. But if anyone nearby wants to take a dip in a very large hot tub, feel free to stop by.

How'd ya figure that?!?

Thanks for the invite, but I have my own down here in Mid TN

Convert both sides to degree*gallons and solve. Lowering 10,000 gallons by 5 degrees is 50,000 degree*gallons. 50,000 degree*gallons divided by 8 degrees is 6,250 gallons.

Okay. I've been trying to determine if my pool cooler sprays are working, or can work, and if so what is the best trade off, volume of water or amount that it gets chilled. I've collected the water from two different types of sprayes, one was cooling 3-4 degrees, one was cooling 8 degrees. It's difficult to collect the water as i would have to catch all the rain, but i think i could make something to do that without restricting flow.

I'm starting to wonder if the pool coolers /fountains/pvc with holes in them really do anything or not. My pool uncovered at night can loose 5-6 degrees on it's own. But will gain that right back the next day. The trick would be to catch it at say 92 and keep it from getting hotter with the sprays/fountain/cooler.

In the above example if your pool cooler cooled 10 gallons a minute you are looking at 10 hours of run time.
I don't think i'm any where near moving 10 gallons a minute with and 8 degree drop, and i doubt anything else is too. Guess i really need to get an idea of volume of water cooled.

15. ## Re: Glitch in the Pool Calculator!

If you run the entire output of your pump through the fountain you will be moving much more than 10 GPM. Pumps vary a great deal, but 40 GPM is a much more reasonable starting estimate.

The home made PVC fountains work, many people have made them and all report noticeable improvements.

16. ## Re: Glitch in the Pool Calculator!

Link to this homemade PVC fountain? I will google, and am considering this "fountain" idea. But it is abnormally HOT here, as we are breaking records. I really don't want to spend a lot as this is the first year I have had a problem.

17. ## Re: Glitch in the Pool Calculator!

Take a look here, here, or here. Those are optimized for aeration instead of cooling, but the only difference is for cooling you want more time in the air, which just means slightly different aiming of the jets and is otherwise the same.

18. ## Re: Glitch in the Pool Calculator!

Jason,

Each of those shows an IGP. How about doing one on an AGP?

The two hurdles i can think of right off are:

1) Would the weight of the PVC filled with water be too much, "prying" on the wall of the pool?

2) My own AGP...and I presume others...has a "non standard" fitting at the return..that is, it's not a standard plumbing fitting. So how to go about adapting it?

I bought this: http://www.amazon.com/Swimline-8598-Flo ... l+fountain

As much because I need to lower TA as the temp... Mary: Even with this, I'm topping 92/94 I'm not sure where you are, but we can't be that far away... I'm hoping the weekend brings us some much needed relief. I may run the fountain overnight if it's going to drop much. (I'm about 25 min east of STL)
