Rated 5 out of 5 by from Best hot tub on the market We have owned other spas in past years including a top of the line “ Marquis” which we thought was the best until we got this’s one. There was literally no comparison.

Rated 5 out of 5 by from Best investment of 2020 We love our hot tub and use it almost every day. It is beautiful and easy to care for. Best thing we did was add the interior light package as we use ours mostly at night. The service from Suntek has been exceptional. We could not recommend a Master Spa more highly!

Rated 5 out of 5 by from Michael Phelps MPL700 spa We owned a larger Master Spa since 2001. Never had any issues other that filter replacement until 2020. Pretty long run for a spa, huh? Family downsized and we purchased the Michael Phelps MPL-700. Holds 4-5 but perfect for 2 full size adults to enjoy multiple stations without interfering with each other. Biggest reason for the upgrade, was the total number of jets this unit has. There is jet for every muscle!!! Only minus is the the layout configuration of the jets and air controls. Still perplexed on why it laid out the way it is! You constantly have to get up to activate the jets, except when in the lounge.

We have had the hot tub for just over a year now and started seeing dark specks floating in the tub. It turns out the pillows have broken down and are peeling chunks into the tub. Our hot tub before this we had for over 8 years and this didn't happen.

Asked by: Jflew
Hello! Are you rinsing your spa pillows as suggested in the owner's manual? This will remove chemical residue and help prolong the life of the pillows. I would also recommend leaving the cover off of your hot tub for about 15 minutes after adding chemicals as the off gas can cause similar damage. Feel free to reach out to our customer service team with any more questions. You can email them at customerservice@masterspas.com or call (800) 860-7727 during normal business hours.

Further to a question by Molly4412, screwing the newly-cleansed Eco-Pur filter into the core closest to the control panel, backing off a 1/4 turn, there is next to no bubble activity from the circulation pump. We put the regular filter there, thoughts?

Asked by: Tedsky
If you have a circ pump you really just need to make sure the EcoPur filter is the one closest to the control panel. If you have any other questions please call (800) 860-7727.

Hi, I asked a question regarding pump specs about 10 months ago but forgot to mention that ours is a U.K. version. It's a Michael Phelps 7 (sold by Blue Wave Spas AKA Hot Tub Superstore). Is the US version more powerful with bigger pumps or the same ?

Asked by: racey1979
The international pumps on the MPL/LSX line would be 2 two speed 10.3 amp pumps and a one speed 10 amp pump.

Does it matter what filter goes on which side? I took my filters out to clean and didn't pay attention to which was where?

Asked by: Molly4412
Hi Molly! Good question. It really only matters if your spa has a 24 hour circulation pump. Our typical standard is to put the EcoPur 2 piece filter set closest to the topside control panel. Hope this helps!

Thanks Kayla, that's very helpful. What are the limiting factors fitting bigger pumps pulling more amps ? Is it my power supply to the spa ? Or the Balboa electrical control components within the spa ? If that makes sense ?

Asked by: racey1979
Happy I could help! Honestly, it could be both - and it's not necessarily something we here at the factory would recommend doing. I would recommend calling your local dealer or our customer service team at (800) 860-7727 so they can discuss the pros and cons in more detail with you. Thanks for asking!

Hi, owned an LSX 700 for 3 months now and over the moon with it. I know the main pumps are 1 x 12 amp 56 frame, 1 x 16 amp 56 frame. In future, could I replace the 12 amp with a 16 amp for more power ? Which has bigger main pumps ? LSX or twilight ?

Asked by: racey1979
Hi! The Twilights have two 12 amp pumps. The LSX has a 16.4A, 12A and around a 6.3A pump. Is it possible to switch out the 12A pump for a 16A pump? Space wise, I believe so. Running all 3 pumps on high speed would be pulling quite a bit of amps, however. Hopefully this helps!

Does each spa come with the clear spinning balls if the lighting package is included?

Hi Joe! That feature isn't available anymore. Thanks for asking!

Our hot tub will not maintain a temperature higher than 74 degrees. A setting reading says the heater is dry. What does that mean?

Asked by: Tenuhsee
Hi! We recommend checking to make sure that you are in ready mode and in high range. I would also check to see if your filters are clean. Dirty filters can cause water restriction to the heater and that can indicate that the heater may be dry. Hope this helps!
