Yes, your dealer can install the MP160 pump upgrade. However, it will likely cost you more money since your dealer has to do the work and order another pump. I doubt they want an extra pump in their inventory. Yes, the MP120 pump is 120V regardless of how the tub is wired. The MP160 is a 240V pump. Should be a drop in upgrade. No circuit board change necessary however there might be some dip switches that need to be changed, which your dealer can do.

Try disconnecting the circulation pump. It gets power almost immediately once the breaker is turned on.

Trichlor, no. Dissolved too fast in warm water and it very acidic. Only Hot Spring I’m aware of that is 6’ x 6’ is the SX which is 285 gallons.

Congrats on the Envoy NXT, awesome hot tub! Curious why you have 3000 ppm of salt in your water when not using a salt system? ACE only requires 1750 ppm, just an fyi. I sell ACE and have had great luck with it. The benefits you should see are no chlorine odor since you are creating chlorine naturally, more stable pH/Alk since you will be adding less product that can influence them and longer life between water changes. That being said, if your previous water care routine has been working for you, I see no reason to switch it up.

As a retailer who has sold @ease for going on 3 years, generally speaking I have had good luck with it. Assuming you do not have a 600 gallon hot tub, my guess is that either the setting was set too high or your pH was really low, both would cause the cartridge to dispense quicker than it should. The Mineral is also only about 1/2 full to begin with and the minerals do not dissolve over time. To the OP, check for copper in the water. Assuming everything is within balance, if there is copper it can react with chlorine or MPS and cause a green tint.

Agree, really low price in the V77 and also a low price on the Beam. All good spas, but I agree with Markee that the Hot Spring and Marquis are a step above the Jacuzzi. You are looking at an entry level Jacuzzi and the middle tiers from Hot Spring and Marquis. FWIW, the Beam has a 5 year warranty, is fully insulated and has ozone standard.

It has to be in the electronics. The pumps only turn on when they are told to. What kind of hot tub is this?

You should be fine with either or. As long as the jet face diameter is the same and the back cone piece is the same with the tabs in the same spot, then brand shouldn’t matter.

I think you would be wise to avoid Master Spas. Too many other quality options out there. Look into Hot Spring, Caldera, Jacuzzi, Sundance, Marquis, Artesian, D1, Bullfrog, and Arctic. No such thing as chemical free. Only EPA approved sanitizers in the United States are chlorine, bromine, and hydrogen peroxide. You can supplement with mineral cartridges, borates, enzymes, and use things like O3 (ozone) or UV, but you still need one of the 3 main sanitizers. Use the dealer locators on the websites of the brands I listed above and find a hot tub that works first, then worry about the chemicals.

Nordic, Viking, maybe Artesian. Unfortunately, $4500 doesn't leave you with many options. I would honestly either save until you can increase the budget up closer to $6k-$7k or look for a quality used hot tub.

That is normal with all hot tubs wired 110v. Heater turns off when pump is on high speed. If you want heat with the pump on high, you need to convert the tub to 220v.

If the flakes look more like fish scale then it is likely scale. If it was either stringy or looked like fish food, then I would lean towards white water mold.

1. With no copper or iron and your hardness where its at, you should be fine not adding any stain & scale product. 2. Your pH and alkalinity are balanced and unless that changes there is nothing you need to do for them. 3. I personally would have just left the calcium alone at 130, but it is fine to increase it into the desired range. 4. No need to use non-chlorine shock right away. Use that later. Super chlorinate with chlorine on first fill. 5. Free chlorine is what you want to maintain between 3-5 ppm 6. Do not use the cal hypo. Only type of chlorine that you should use is di-chlor 7. DO NOT USE chlorine tabs. They are very low in pH and will dissolve rapidly in warm water. 8. No idea on converting grams to other measurements. Water temperature is irrelevant to the water chemistry. However, chemicals will react slower and dissolve slower in cold water. Also, aeration will naturally cause pH to rise and any time your jets run they are aerating the water. The result will be fluctuating pH over time.

I would be asking the seller why they are selling something brand new for so cheap, especially when it is a current part. Hot Spring stopped using the exterior control panel with brainbox after 2007. If you went ahead and tried using that control box you would also need the digital control panel. The digital control panels are meant to be mounted on the hot tub shell which there would not have been a dedicated spot on your Landmark. You would have to cut a hole in the shell to mount it and fabricate a platform for it to rest on since you would have to recess it so the buttons don't get pressed every time the cover is shut. Lastly, you would need the appropriate software file since the control boxes don't function without it. It's going to be a lot of work and headaches to get current electronics working on that hot tub. I personally would not do that and either spend the money for the correct electronics or be patient and see if something used appears on ebay or craigslist.

The newer electronics will not be compatible with the older electronics. Your exterior control panel, the brainbox behind it, the aux control panel and maybe the light will not be compatible. I'm curious what you are finding for $225. As a Hot Spring dealer, my wholesale cost is more than that.
