If this is the way your husband thinks, he is perfectly normal. Very few husbands initially want to even look into the possibility of installing an inground pool. This is a misconception that many husbands have of thinking a pool is a lot of work and they do not have time to do the required maintenance.
Pools are not like they use to be ten years ago. The inground pool is very easy to maintain and requires very little time each week to keep clean. Your pool will require chemicals and which chemicals you use will determine your weekly cleaning time. Look into installing a Chlorine Generator (salt system).
With a salt system, the pump will not have to run 24 hrs. a day seven days a week. Your pool water will be a lot cleaner requiring a lot less of your time having to vacuum. Your chemical cost will be a lot less. You will have more time to enjoy the pool and not worry about cleaning. If you did not want to manually vacuum the pool, look into the many options for automatic pool cleaners. The pool now can become the focal point of a family vacation in your backyard everyday. There is nothing like coming home from a hard day at the office and unwinding in your pool. Your husband will love this after he tries it one time. Listen to the water, maybe turning on some music, cooking on the grill, no traffic. Just ask your husband to visit your local pool dealer to look into the many options available today.
Please note: results of various water treatment systems and filter times will vary. Consult your local pool professional for complete details.
