A cheaper alternative to Grocery Store Baking Soda....

Makes sense if that is an issue where you are located. Actually you get more cooling from the evaporation than from adding the tap water!

Maybe so, theoretically--but practically, when I run the slide with 60 degree tap water during a 3 or 4 hour swimming session, it drops the temp of the pool very substantially, where we don't really notice a cooling difference from the evaporation. Maybe it's because the humidity is usually high 80's-100% most of the time. Dunno....I just know that by mid August or so, the kids are complaining because it's too hot to swim!

Well you are probably just feeling the water temp right where you are adding the water. Here is the math. When you evaporate one gallon of water the pool loses 8500 BTU of energy. When you replace a gallon of 90 degree water with a gallon of 60 degree tap water you are cooling the pool by about 250 BTU of energy. Thus, the one gallon of evaporative loss is equivalent to about 34 gallons of cold water added.

OK.....not arguing with you over it!

I like the warm water, guess it's a side effect of growing up in Miami and spending a lot of time swimming in the Keys. The ocean water was always very warm in the summer until you got out a bit from the beach. It was like getting into a bathtub. We just expected a pool to be in the high 80s in August!

What I CAN'T get used to is when I vacation up in Cape Code and the pools are not heated. NO pool should be in the low 70's in July or August! It's just nor right!

Agreed! I just wish my pool would stay in the low 80's. I am installing a shade sail over the shallow end in the next month or two...if it mitigates even the perceived notion of "bathtub water" it will be worth the cost. I am also considering selling and installing as well!

OK, I'll bite. What is a "shade sail" exactly? I get the gist that it's some kinda shade.....but never seen one for a pool.
