For those of you with pools at your house...

We have a good size pool at our house, and when the pump is on, it roughly adds about $100/month on the TXU bill.

Once a month, we take a sample of the water to Leslie's Pools to test it and they tell us which chemicals we need to add or stop using.
We spend an average of $50/month throughout the year in chemicals.

Then of course, you either do the maintenance* yourself or you pay a company to do it every week... a good maintenance will save you lots of money (mostly in Summer time), if you neglect your pool, be ready to have some extra costs.

* Taking the leaves out, cleaning filters, emptying baskets, add chlorine tablets...

During summer in Texas, because of the heat, you get algeas very quick. So be sure your pool's water has all it needs in order to avoid that green crap
