"There is absolutely no question that I'll be calling Black Diamond again with any of my spa needs. I contacted a different place here in Longmont and made the mistake of not reading the reviews first. A week later, without hearing back from the first place, I reached out to Black Diamond. Brian got back to me that evening and promised to squeeze me in the next day. He lived up to his promise and showed up that evening. He completed the repairs in a very timely manner and communicated throughout the entire process. If you need any sort of help with a pool or spa, I definitely recommend reaching out to Black Diamond!"

"These guys are terrific by any measure. Professional, courteous, and their work is very diligent. Prolific Pools and Spas is a first class outfit in any circumstances, but given how hard it is to find even passable pool and spa help in Northern Colorado, they are truly a breath of fresh air. I will be their customer for as long as I have a spa."

"Michael was the absolute best. Designs by Sundown quoted me an insane price and lied about what needed to be fixed. Michael came in, was honest, fast, and did high quality work. He’s my pool guy forever now."

Pool and Spa Servicing FAQs, answered by experts

To refill a hot tub after winter, start by opening up the tub and giving it a quick cleaning. If you use antifreeze, drain out the water then grab a hose and thoroughly clean the tub shell out, spraying water into each jet of the tub. 

Reconnect the hot tub and turn the power back on. When it’s time to fill the tub again, insert the hose into the filter well (if available). Avoid trapping too much air in the water lines, which can cause the pump to lock up when it starts again. Add the necessary chemicals and start the heating process. It will take some time—most of a full day—for the water to heat up again.

The best thing with which to clean a hot tub is whatever the manufacturer recommends; in most cases, this is a gentle surface cleaner and a soft cloth. Recommended hot tub cleaners can include specially formulated cleaning agents, mild dish soap, baking soda, vinegar, or diluted bleach. For your hot tub exterior, choose wood or vinyl cleaner (depending on the casing material).

You should never use household cleaning products, harsh chemicals such as undiluted bleach or acids, or abrasive cleansers or cloths, as these can scratch or etch your hot tub’s coating or shell and cause permanent damage.

You can and should use a hose to fill a hot tub. There shouldn’t be anything special about the hose other than it shouldn’t be damaged. Kinks or leaks could slow down the filling process. Attach the hose to the nearest spigot and get the water flowing.

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

Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.
