What our customers are saying
Ordered an open box salt cell and it arrived quickly and in perfect shape. Literally, the only thing that made it open box was the security seal on the box was cut. Great price on a new salt cell. Thank you!

They had the best on-line price which beat my pool maintenance guy's wholesale price and it was in stock. It was also delivered the next day by a very nice gentleman who phoned ahead telling me he was on his way. I will absolutely buy from this company again if the need arises.

FAQ
Our expert staff answers customer's most asked questions.
Do you offer warranties?
Yes. We offer extended warranties at check-out.
Should I cover my spa or pool with a custom spa cover or solar pool cover if I am heating my pool?
Yes, it is advisable to cover your pool when heating it. Failure to do so allows generated heat to escape, causing the heater to work harder and resulting in higher heating costs. Consider using a custom spa cover or solar pool cover to optimize the efficiency of your heating system.
How many BTUs does my heater need to heat a pool or spa?
The ideal BTU rating for your heater depends on your desired heating speed. A 200 BTU or 250 BTU heater is suitable for a spa or pool, while a 400 BTU heater will heat your pool and spa more rapidly.
