Swimming pools have a huge influence on your home and the way you spend your free time. It can be the center of recreation for you and your household, a source of pleasure and relaxation, a beautiful centerpiece for your yard, and can increase the value of your house and property significantly. Pool owners also know that these advantages don’t come without cost and effort. It can be a challenge to

maintain thousands of gallons of water in a constantly changing environment, keeping it free of algae and pollutants, balancing water chemistry, and cultivating that pristine sparkle that makes your pool so inviting. Owned and managed by Dave Gust, Dolphin Pool and Spa has made a mission of helping families enjoy their pools and get the most out of their investment, everything from building vinyl in-ground pools, to renovations, to providing regular service and maintenance on water and equipment. And as the name suggests, they also sell and service acrylic spas.

“We offer custom lighting and water features to spice up your existing pool design. Our newly remodeled retail store includes new stand-alone spas, pool and spa parts, and chemicals and accessories,” said Gardner. The retail location in Plymouth is also home to their experienced service department, trained to partner with pool and spa owners, addressing their individual needs and helping manage the issues that come with Minnesota weather. In recognition, Dolphin Pool and Spa received the 2020, 2021, 2022 and 2023 Sun Readers’ Choice Award for being the number one best hot tub and pool store.

“We have established an outstanding reputation for quality products and service. Credit for this goes to everyone one of our employees,” said Gust. “Dolphin Pool and Spa has been in the same location since 1979. In those 38 years, we’ve amassed a sizeable group of trained, longtime employees. We take care of our employees because without them we could not fulfill our purpose: making pool ownership a joy.”

Though based in Plymouth, the service department covers the entire metro area, providing full cleaning, maintenance, and repair. “We specialize in vinyl liner repairs and replacements, as well as coping and tile repair, pool equipment repair and upgrades, and pool cover repair and installation. Our techs take before and after pictures and email our customers an update as soon as we are finished with the job,” said Gardner. One of the company’s core values is knowledge, that is why they have made information and education a priority believing that the best, most satisfied customers are the most knowledgeable. Their YouTube channel (YouTube.com/c/dolphinpoolandspa) highlights short, fun videos that explain and demystify pool chemistry and equipment, and an annual “Pool School”, held in their retail store, is taught by a representative from BioLab, the company’s pool chemical vendor. They also sell the full line of Rippling Water Spas, from large family spas to hydro-therapy spas offering targeted massage and full body rejuvenation.

Chemical levels can only tell so much of your pool's story.

A picture helps identify how large or what kind of problem your water is facing.

So next time your pool has a problem and you go to get the water tested, quick snap a few pictures. This allows the tester not only to see progress (if any has been made) but also identify the best path forward.

Considering a fall stock up on chemicals?

One week is left to get $20 BACK for investing in your pool.

So if you have been waiting to buy a closing kit or replenish your supply of pucks now is the best time to do it!

If your liner is needing to be replaced a clever way to start your spring is to replace your liner at your opening.

Replacing your liner in the spring means:
More time with your pool when the weather is warm
Starting the summer with fresh water so you don't have to fight algae
Flagging structural issues before the craziness of summer
Fixing equipment early so it can deal with all summer brings

If you want to join the list of spring liner replacements call us! 763 336 2521

When is the best time to close your pool?

With the weather cooling down and the pool falling in the priority list a lot of people shut down their pool right after Labor Day. It is convenient and it loosens up your schedule.

But most people don't consider what happens to the water when the cover goes on.

With no circulation, filtration , and without consistent sanitization, algae can find a perfect time to grow. Especially when the temperatures rise again late September and early October, your pool can turn green for the spring opening without anyone noticing.

How can you help prevent that surprise pool opening? Schedule the closing for early to mid October.

One problem with closing in October.

Leaves.

They can turn skimming your pool into what feels like a part time job. And there is the consistent testing and chemical checks which go along with keeping your pool operational.

So when is the best time to close your pool?

It depends.

If you want the lowest possible chance of a green pool? Close in October
If you want to end the pool season when you stop swimming? Close in September

If you have not scheduled your pool closing, give us a call at 763 542 9000. Scheduling it can be as simple as a four minute phone call!

Every year winter tires to kill your equipment. The cold. The wind. The snow.

So how can you help protect against that?

Pool Closing Complete conditions the pool water to help extend the life of your equipment and pool surfaces. So that means longer lasting pumps, heaters, filters and smoother openings.
