"Great working with Angelo and his team. They did a fantastic job of repairing pool leaks, coping, tile, and completing the area around the pool. They cleaned up after themselves, were approachable, hard-working, and courteous. I will hire them again!"

"Juston he is amazing! Poseidon pool service company is a big reason why we started using their service but Juston is the main reason why we stay with this company. They service our pool to a level like Iâ  ve never experienced before. Iâ  ve owned many many pools in my lifetime and Iâ  ve never had such a good quality of pool service at a great price. Cole the owner is fantastic but nobodyâ  s as good as Juston"

Pool and Spa Servicing FAQs, answered by experts

Regular water testing, filter cleaning, and chemical balancing are essential for keeping water clean and equipment functional.

Yes, they provide full-service inspections, identifying and resolving any potential equipment problems.

When your hot tub is completely dry, there is typically no need to introduce antifreeze into the plumbing. However, if you desire an extra layer of protection against potential freeze damage, you can consider adding some RV antifreeze to your hot tub lines. Just ensure that you use RV antifreeze specifically, as automotive antifreeze is highly toxic and should be avoided.

You should put chlorine in your hot tub on a regular basis. To keep bacteria away, keep the chlorine level in your hot tub at between 3-5 mg/l, which may mean you need to add chlorine daily or at least every two to three days. Don’t add chlorine to your hot tub water more than once per day.

Follow these general safety tips for spas and hot tubs:

  • Keep your exterior electrical receptacles covered and dry, especially around your hot tub and pool during periods of use.

  • Make sure you have a GFCI (ground fault circuit interrupter) properly installed to ensure no one gets accidentally shocked or injured by electrocution. 

  • Don’t use the hot tub or your pool during a thunderstorm. 

  • Before using the hot tub, have a certified electrician thoroughly inspect your hot tub and its wiring to make sure you’re in full compliance with all applicable local building codes.
