First of all, as a pool owner, I think the idea of discovering a rubber duck in my pool is a bit intrusive, especially because I have kids and security is a concern for all of us. Maybe you could use that same theme, but leave it at the front door?
Now on to your advertising question... As the owner of a business that not only advertises, but also sells advertising, I would strongly suggest becoming informed about your particular business and who you'd like to target. All too often, we see business owners who spend money on advertising with other publications, then are disappointed when they don't get results. Some tips I would suggest...
Learn who your target is. I'm sure there are professional organizations like http://www.apsp.org/default.aspx or http://www.upsaonline.com/ who have some statistics to share with you regarding pool purchasers. Are they typically young couples? Families with young children? What is their median income? Which communities if the metroplex have the most pools? Are there any communities which seem to be underserved? Then target your ad dollars to those people in those locations. Either find a local publication that specifically targets your group, or ask a company that offers regional advertising (such as ValPak or Clipper Magazine) how much they can narrow down their distribution of the ads you purchase - you don't want to pay for a regional campaign, where a large portion of your ads are going to homes with an income well below your target, or an age well above your target.
I would also work on what you're going to say in your ad... Be as concise as possible (people don't want to read too much verbiage) but HAVE A PLAN. All too often, we see business owners who want to use their business card as their ad... not a good idea. Play to the readers dreams and hopes (entertaining, fun with the family, etc.) Ask them a question in the ad to get them thinking (Do you have a HOT wife - obviously only works if married males are your primary target). Give them a teaser, then close with a call to action. Many publications will have someone on staff to help you put together an ad, but you can also visit the library and check out a few books on the subject. Again, the smarter you are about what you want, the better results you'll get.
Think about (and ask your friends if they're in the demographic you're looking to sell to)... what advertising do you look at and what do you dismiss. This applies not only to the type of ad, but also how it's delivered to you. Do you go through the envelope of coupons you receive? When was the last time you looked at a yellow pages ad? Do you look at the free newspapers you receive in the mail? When you receive a letter that's personalized to you, but you don't recognize the company, do you open it or toss it?
Most will agree that your ad needs to be seen multiple times, and you need to build a relationship in your communities before your ads will be effective. Don't go into this with the belief (as many do) that if you place an ad or two, business will start flowing in. You'll be disappointed. Plan on building your brand name. You might consider spreading your ad dollars over a longer period of time, rather than a full page ad one time. We always recommend that people do NOT advertise weekly in our publication (we have a weekly newsletter). If people see your add week after week, they tend to gloss over it. Our advertisers will have a good response the first few weeks, then it will taper off. Advertising once or twice a month in a weekly publication will help spread your dollars out and keep it fresh for the reader.
People also need to believe you're going to be there if they have a problem down the line. That being said, even if this is a new business, use your experience/longevity in your ad if you have it (15 years in the pool industry - if your husband has been working for someone else for a while... or 15 year resident of Plano (if you've lived there a while)).
Also consider how you can get free advertising? Maybe you conduct a free seminar for people at the local rec center... A Parents Guide to Pool Safety or Guidelines for Your First Pool. You'll be viewed as an authority in your community, and get free marketing through the rec center activity guide.
Again, the best advice I can give you is to soak up as much info as you can through books, internet, friends, etc. And get out there and network with other business owners... they're probably not going to buy a pool from you, but they'll give you wonderful advice, and maybe a referral or two.
Good luck! I know what a daunting task it is starting a new business.
