Rated 3 out of 5 by from Great Hot Tub, Filters cause air locks I will say I do love my spa, but the filters are always causing air locks, even brand, new clean filters, in a few days I get an air bubble and it stops heating and circulating. This is especially annoying in the winter because I have to go out and keep fixing the air lock for fear the temp will drop to freezing. I have completely drained and refilled the tub and put in all new filters and it happens over and over. Other than that, it is a great spa and I do love it.

Rated 4 out of 5 by from We LOVE our hot tub! We love our hot tub! The only negative about this whole purchase experience was the miscommunication about the fact that we had to install and set up the unit ourselves. MasterSpas -- you are missing the mark on this customer service "opportunity". The spa was merely "delivered and set down in the spot where we wanted it placed and the packaging trash was hauled away". We were told that hard wire installation and initial set up was our responsibility. I will say that our local representative (Austin) was very helpful, courteous and professional in all of our dealings with him from delivery scheduling to answering our many questions after delivery -- Austin, we DO appreciate you very much!

Rated 3 out of 5 by from Problems with holding water I love the hot tub itself. The jets are wonderful. Unfortunately we have now had 3 service calls because the tub is losing 2 inches of water a week. Each time the foam has to be removed. The dealer has taken weeks at times to respond.

Rated 1 out of 5 by from Nothing but problems I have owned a hot tub all my life. I know how to maintain them. My last one lasted 15 years with no issues. But needed something bigger. I went into a highly recommended business and asked for the best money could buy. Worst decision. It locks out on dry pump constantly. My filters are new. I have used many different filters trying to get it to work. My dealer has been out numerous times and no remedy. The bluetooth is a known joke. The wifi has never worked right.

Rated 5 out of 5 by from Excellent Hot Tub We got the hot tub recently and we've been using it daily. Nothing but fun. I am surprised at some reviews that complains about air locks and the sound system. If you fill it the right way (through the filters), you'll not get any air locks. As for the sound system, it is awesome!! There was a minor issue with the lounger's Jets button. I called my dealer, Crocker Sales in Woburn MA, the technician showed up the same day and took care of it.

Rated 5 out of 5 by from MPL 900 - Great Hot Tub Wasn't looking for a hot tub but stumbled on this Mac Daddy during a visit to a trade show. Loved all the features and the number of sitting areas and multiple jets in each location. Was easily installed and up in running very quickly. All the controls are easy to use and simple to understand. The sound quality is A+++. The family uses it constantly and is well worth the value.

Rated 3 out of 5 by from Master SPA is ok We wanted a Master SPA since the one we had back east worked for over 15 years and had little problems. We bought a new one on the West coast and learned if you want any warranty work done you have to pay $90 for someone to come and look at the issues. The sun has warped our skirting and have WIFI issues and rust on speaker screws. Other than that, it works as expected.

Rated 5 out of 5 by from Great hot tub!!! We use our hot tub pretty much every day in the fall and winter, and usually 3-4 days a week in the summer. I'm a former power lifter and my body loves soaking int he hot water and getting massaged by the jets. My wife also loves the way it relaxes her after a tough long day at work.

  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!
