"Joe is Shark Pools. He has eons of experience about anything to do with pools and especially pool liners. So as a new pool owner, Joe has been gracious in tutoring this novice on what to do and the why to ensure the best life out of my pool liner and pool experience in general. His work is superb and pricing more than fair. Joe is old school, meaning he does what he promises and exceeds all expectations. My wife and I not only got a wonderful pool renovation, but gained a life-long friend in the process."

"I went with them because they were highly rated and significantly cheaper. I’d do it again. A couple of minor missteps because of communications which could be taken care of by a decent outline of expectations. They put the customer in charge of draining and filling pool. I’ve had liner pools for 40 years and replaced at least 4 liners but I worried over what could happen if I drained the pool too early and was told to drain it dry (that doesn’t really happen). I was also told to fill the pool while it had wrinkles I worried but they were right. There were a few things in between that they could have been headed of with a decent outline of expectations. Overall I’m very happy but it was some unnecessary worry on my part. I would be happy to help them develop outline if they’re interested."

Pool and Spa Servicing FAQs, answered by experts

No. In fact, some owners prefer to “summerize” their hot tubs and use them primarily over winter to enjoy the contrast of cold and hot water. It’s possible to keep the tub filled and running year-round, and some pros may even recommend this method compared to the work and risks of a full winterization every year.

However, keeping the hot tub running will require additional resources. You’ll use more power and more chemicals to keep it in good shape. Weigh the pros and cons of your situation before making a decision.

Yes, hot tubs can use a significant amount of electricity, primarily to keep the water heated. A typical hot tub uses between 1,500 and 6,000 watts, and the pump can add another 1,500 watts. This usage can result in a monthly cost of around $20 to $30. The exact amount of electricity consumed depends on several factors, including the hot tub's age, size, heater voltage (120V vs. 240V), usage habits, and thermostat setting. Newer, energy-efficient models generally use less power than older ones. To reduce electricity costs, consider investing in an energy-efficient model, using a quality insulated cover with a thermal blanket, and keeping the filters clean.

Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm.

Shocking your hot tub means adding extra chemicals to the water. Most spa experts recommend doing this once a week for proper hot tub maintenance, but you can do it more if needed. Shocking has multiple benefits, including preventing the water from becoming murky and it’s essential in removing harmful bacteria from the water.

In most cases, it is safe to clean a hot tub with vinegar. You will want to verify that your hot tub manufacturer lists vinegar as a safe cleaning product; however, given that vinegar is chemical-free, cleans, deodorizes, and is safe for people and pets, it is usually a good option. You can use vinegar to clean the hot tub shell, interior and exterior spa surfaces, hot tub jets, hot tub filter, and other parts. It is considered a strong, safe, and natural cleanser that can kill bacteria, remove mold and mildew spores, erase water spots, and remove hard water stains.
