Rated 4 out of 5 by from Best Investment Ever! We love our new Michael Phelps Jacuzzi. It is large and spacious! We did have a small leak, but a technician came out and fixed the problem in a matter of days. The only thing I wish it had more cup holders around the entire system, not only on one two sides

Rated 3 out of 5 by from Nice Spa, nothing but trouble though.... The hot tub is nice and large for groups and entertaining. However, we continue to get air locks like others have complained about. We have trouble with balancing the water constantly. Have had to drain and refill my tub constantly, have had a technician out to fix the heater that's gone out several times. Had to replace the speakers, all the jet controllers and all the speakers which was not cheap and all this happened just outside of our warranty period. All started with the heater blowing the breaker constantly right after it was installed. Found heater was bad. Easily replace but service took almost a month to get to it. Got heater fixed but within 4 months started having heater issues again. Took another month to get it serviced after our service call. Had to order the heater core. Then chemicals got out of hand and burned all our internal equipment - techs blamed us for the chemical imbalance. Constant issues - more than I expected. I owned a pool for 7 years and never had these issues. Was told a hot tub is easier to manage than a pool - not so much.

Rated 4 out of 5 by from My New LSX 900 We really enjoy our LSX 900. It has a ton of power and features that you will not find on other spas. The warranty service provider came out and made the necessary adjustments and it is working beautifully.

Rated 1 out of 5 by from Very dissatisfied. The spa hasn't worked right and has been leaking since the day it was delivered. Rather than give us a new spa, you have chosen to drag out this repair several months.

  Purchased a brand new LSX 900 that just got delivered and we did not get the two round ball Spheres for the water feature 

Asked by: Shanlee
Hi! That part is not something that we are using on newer model tubs due to issues that we have seen with them in the past. If you are still interested in them, however, feel free to email us at customerservice@masterspas.com with your serial number, and we could send you out a set.

just got our 900 michael phelps legend spa set up and trying to figure out my chemicals . i tested the water as soon as i got the spa filled.  it is showing the PH is level but the alkalinity is substantiallly high..... what do i add as start up??

Asked by: trina
Hi Trina! To start your chemicals you will typically receive a chemical that is a mineral or metal protect. This chemical should always be put in first. It should be run through the system for about 12 hours. After the twelve hours, you will want to make sure your pH and alkalinity are within the normal range. For this you will use pH up and down or increaser and decreaser. Alkalinity and pH usually will behave in tandem with each other. There are a couple ways to get the alkalinity to go down. The first is to bottom out both the pH and alkalinity with pH down, then build them both back up with the pH up. The second is to purchase a chemical named 'alkalinity down'. This chemical would only affect the alkalinity. After you have these two items balanced you will then put in your chlorine. The recommended on start-up is two ounces. After that, you will want to add a teaspoon after every use. Oxidizer or shock, and scale defense will be items for weekly maintenance. Add in the recommended level of each item once a week to insure the clarity of your spa water.

One of our lights has turned red instead of blue or green. Is this a problem?

Asked by: Dana
Hi Dana! It sounds like one of the plastic LED light housing may have cracked. This would allow water to leak on the LED light. The light and the LED housing should probably be replaced. Thanks for asking!

Just received our LSX900 (ordered 5/2017, delivered 8/2017). Ur website notes orion light system that allows it to change colors? Ours does not...? Also, do you have a schematic of which on/off valves do what?

Asked by: jscheeler
Hello! The lights do change color! Just press the "light" button continuously (waiting no more than 5 seconds between button pushes) until you reach the color you desire. Hope this helps!
