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.

β€œWe 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.

β€œWe have established an outstanding reputation for quality products and service. Credit for this goes to everyone one of our employees,” said Gust. β€œDolphin 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. β€œWe 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 β€œPool 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.

πŸ§‚ Got a saltwater pool? Closing day works a little differently.

Most of the closing steps match a regular pool. But a salt pool has a few extras that can cost you in spring if you skip them. A cracked cell housing is not a fun surprise.

Our new article walks you through what changes: balancing the water, why the salt stays in the pool, how to pull and clean your salt cell, and which BioGuard products to add by hand once the cell is off.

πŸ‚ Mesh, Bag, or No Cover? Pick Before the Snow Flies

πŸ”§ Is Your Pool Ready for a Minnesota Freeze?

Water expands when it freezes. Inside a pool pipe, that can mean a crack, and you may not find out until spring. Blowing out your lines clears the water and protects your pipes.

Our new article walks through both options. You'll see the DIY steps, what to buy, how a Dolphin closing compares on price, and what we need from you before we arrive. It also tells you when to call a pro.

πŸ₯Ά A cracked pump is an easy spring surprise to avoid

Minnesota winters are hard on pool equipment. Any water left inside a pump, filter, or heater will freeze, expand, and crack the housing. Fixing that in May costs a lot more than an hour of work in October.

Our new article walks you through it step by step. You will learn how to drain the pump, how to winterize sand, cartridge, and DE filters, and how to use a shop vac to pull out the last water and push air through your lines. We also cover the small parts people forget, like the heater, the gauge, and the salt cell.

πŸ§ͺ One last check before that cover goes on.

A lot of pool owners think closing is done once the furniture's stacked and the cover's folded. But water left unbalanced under a cover keeps reacting all winter β€” pulling minerals out of your plaster or dropping scale onto your liner, right up until you open it again in spring.

Our latest article walks through the last balance to run before you close: setting pH, alkalinity, and calcium hardness with the BioGuard Balance Pak line, shocking the water, and finishing with an algaecide so you don't open to green water in April.

❄️ Time to Close Your Pool the Right Way

Skip a step during closing, and you may find a cracked pipe, a stained liner, or green water waiting for you in spring.

Our new article covers the full closing checklist: timing it right, one last clean, balancing the water, winterizing the pump and filter, blowing out the lines, and choosing a cover. We'll go deeper on each step later this month.

πŸ€– Leaves Sink Faster Than You Think

Every fall it's the same story: you net the surface, feel good about it, and a week later there's a layer of leaves on the pool floor. Sunk debris breaks down in the water, feeds algae, and eats up your chlorine before you even notice.

We put together a rundown on the tools that handle it for you β€” the solar-powered Skimmi 300 catching leaves before they sink, and the T2000 or Eon 100 covering the floor, walls, and steps once they do. Set it up once, and you're done chasing leaves for the season.

πŸ‚ Leaves, Acorns, and Algae: September's Debris Triple Threat

If your pool looks fine on Monday and green by the weekend, debris is probably the reason. Fall leaves and acorns break down fast, and that breakdown feeds algae faster than you'd think.

Our latest article covers how to handle all three: why wet leaves stain and feed algae, how acorns can dry out your pump, and a simple daily and weekly routine to stay ahead of it. We also cover a fix for acorns clogging your skimmer basket and a solar-powered option if daily skimming isn't in the cards.
