Water Temp

[waterbear]

I am in S. Texas - same problem.

I've often thought about what adding dry ice the pool water would do to it. It is certainly cold enough, but I can't find anything that tells me what (if any) chemical changes it might make to the water.

Any ideas?

might raise the TA and/or lower the pH. The carbon dixoide will dissovle in the water and form carbonic acid which is part of the TA buffer system and also has an impact on pH

Here is an idea. If you buy a hot tub air pump and plumb some pvc together with a horizontal pipe running about 10' along bottom of pool several holes drilled in it and an end cap you could cool the temp during the night possibly. I get this idea from a friend who has hooked up the same stuff to steel pipe running through his wood burning stove and the heated air then is blown into house with the hot tub pump which you can control the speed of.

Anyone have any experience with one of these evaporative cooling systems?

For $36 bucks it may be worth a try. Our water temps here in south Texas yesterday were at 96 degrees. Talk about a large hot tub...

Not sure it would work but it is cheaper at

I would have thought that a couple of cooling fans run at night over the pool surface to help evaporate the water would work.

Advantages are:

1. Don't need to run the pool pump.

2. The air temps at night are cooler.

3. The higher water temperature helps to increase the evaporative effect.

Just make sure that the fans are connected through a GFCI outlet.

Hope this helps.

I just ordered 2 of these devices. I hope they work as advertised. I will post back my experience with them and let you know if they work or are bogus.

I received the pool cooling devices today. I will try to install them tonight and see what they do. I will let you know. BTW-if you buy 2, the S&H is free.

I will be interested to see if they work.

Keep us informed.
