Reducing Chemical use with Enzymes

This article is to look at Enzyme systems and in particular Spa Marvel. This is the system I use on my own Hot Tubs and a lot of my customers have been using it for a long time as well, Spa Marvel makes a big difference in water quality and health and at 54.99 every 3 months is also more affordable than other systems.

So what do they do? Enzymes work by helping to break down inorganic contaminants like sweat, body oils, lotions and other contaminants, the kind of stuff that bacteria feed on and that foam and cloud up your tub. This process has a ton of benefits, enough to justify using a list later, but the main reason this is so important is that they let you heavily reduce the level of chlorine or bromine you use and expose yourself to.

Chlorine or bromine are used for water treatment because they are simply great at killing organics, which is perfect for bactera or viruses but not great for people, especially since the steam from a hot tub gives it easy exposure to your lungs and eyes. This can cause irritation and other issues, especially if you use your hot tub daily like I do, safely cutting down on chemical exposure has always been important to me and right now this system is the best for it.

I know some people totally stop using chlorine or bromine in favor of systems like this but that is pretty risky. These chemicals do play an important role and it is safer to keep chlorine present in the tub even if this treatment lets you use less, Spa Marvel itself is not a sanitizer. Always check your local regulations or recommendations, most don’t take into account systems like this yet sadly but the Enzyme technology is growing popular even without it so hopefully they catch up soon.

Even if you don’t reduce your chemical use here is that list of other benefits I mentioned.

-Enzymes help prevent scale, bio-film and other buildup.
-By removing contaminants that bacteria feed on Spa Marvel reduces the levels of chlorine or bromine needed to effectively sanitize.
-These systems are non toxic and environmentally friendly, the Spa Marvel people even do a demo where they drink it.
-All these above parts keep your total dissolved solids count low which lets your water last far longer before needing changed
-By breaking down and removing these contaminants as well as reducing chemical use your water also becomes easier to balance an can be left for longer.

You can buy Spa Marvel and try it out at no risk, once you see how it helps your water I’m sure you will stick with it.

Thank you for all the information on this site! We are thinking of switching to an enzyme system, we have the Jacuzzi J-345 (it came with the house we bought). For the past 2 years we have struggled with water maintenance. We used bromine tablets and non-chlorine shock then after my husband developed a skin irritation, we switched to a mineral stick and non-chlorine shock. We discovered that my husbands skin irritation was from the non chlorine shock. We switched to minerals and chlorine. That worked great, no skin issues, for 3-4 months. We drained, filled and started up with… Read more »

Hello – love the site, tons of great information. I have just purchased a Master Spa TS 8.25, awaiting delivery in the next few weeks and want to get into a “Proper” Maintenance routine right out the gate. In my research (mostly through your site and other YouTube videos) I have run across Spa Marvel, AquaFinesse, and the local dealer where I bought the tub sells “Spa Solution”. The local dealer claim all three are the essentially same which I don’t buy, so I went to one of the largest spa shops in the area which carries Spa Marvel. They… Read more »

Hi Chris. So first off Aquafinesse (and minerlux and several others) are not Enzyme systems they are mineral systems, for a long time I refused to endorse anything but these systems because they worked the best and I had tried spa perfect and other enzymes and they simply did not perform anywhere near as well. Spa Marvel pestered me for a year to try their… I refused because my experience with enzymes was just not positive and I did not have time. Finally, I relented and tried it… it’s awesome and worked every bit as well as the mineral systems… Read more »

Thanks, I’ll be putting my order in today…

We have a Calspa hot tub. Previous owners used Bromine, and we just started the hot tub with the clorine. This is an indoor hot tub and the clorine smell is REALLY strong, even with the cover on! Would the Spa Marvel work in this hot tub, and would the horrible smell be mostly gone?


Right now yer running 3-5ppm of chlorine with the soap marvel you will run 0.5ppm like the water put of your tap.

Buy it off my site and hit me up for the tip sheet. If it does not work for you I’ll refund it. It’s the best shit out there. Just use the search bar on the site


Chris, Thanks for all the great info. I’m planning to go to the Portland show this weekend and but either the 6.2, 7.2, or 87.3. It is interesting that the 7.2 and the 87.3 have almost the exact same water volume (305 vs 310 gallons) although the 87.3 is much larger and has 3 pumps instead of 2 for the same amount of water. I’m guessing that the seats must sit higher in the 87.3 in order to have the volume the same in this larger tub. I plan to use Aqua finesse and/or Spa Marvel from you but I… Read more »

Hi Michelle

No don’t order AF order spa marvel here:

No Do not order any of the upgraded chem reduction systems

No do not order quiet flow

Biomagnetic is good and it’s free and standard.

ill send you a follow link ๐Ÿ™‚


Thank you so much for all of the information! We are taking delivery of our Master Spa Twilight 8.2 today! We have never owned a hot tub or a pool so I’m very nervous about the maintenance and adding the right chemicals. We did purchase the Mast3rPur system. Which chemicals do you suggest for that spa? Any advice or cheat sheets are greatly appreciated!

Hey Bill.

Im interested to see what they recommend and if it works ๐Ÿ™‚

My experience is that they oversell these upgrades and you still need chlorine if that turns out to be the case get spa marvel… its idiot proof and keeps your water clear and low chem and gives you a lifetime guarantee on the jets.

i would love you to stick with their routine and send me updates ๐Ÿ™‚ then if you have issues try my solution and see how it works. but if you want i can jsut set you uo with it off the bat ๐Ÿ™‚


We’re also looking at the 8.2. So would you not need less chemicals overall with the MasterPur upgrade? Thanks!

Hi Debbie Yes, you would and the Master Pur is UV tech with ozone so its one of the better on bard systems but… The one thing that no hot tub manufacturer or retailer wants you to know is this: None of the systems on any ho tub of any brand is anywhere near as good as the aftermarket add-ins ๐Ÿ™‚ I would never order any of the chemical reduction upgrades, Just buy this shit… its cheaper, lower chem, healthier, natural, makes your water way easier to manage and the water stays clean and clear 3x longer… It also has… Read more »

Right now I have weekly shock with โ€œrenewโ€ and the spafrog floating system, along with weekly filter cleaning with the hose. Thatโ€™s about it. Iโ€™m new at this and like you chris, would like to enjoy this daily for many years and would like to support your informative site.

Thanks for the info on SpaMarvel. Water out of tap tests ph 7.3, alkalinity 150, 0 hardness, total chlorine 0.1. My dealer said that if I use chlorine tablets in the hot tub it would cancel the warranty because they are so acidic, is that correct? Recommended bromine tablets instead. Also would stain and scale control be used? Should I worry about calcium control? Can you clarify that for me? Thanks much!

yeah Tri-chlor is hard on the spa for sure bromine is fine, I find with tri-chlor in these low dosages it’s not an issue but best to stay with approved sanitizer. you dont need scale control with Spa Marvel


Good info. I will order some.

When you shock the spa after use, do you recommend chlorinated shock, or the non-chlorinated variety?

Non-Chorine for sure! and leave the lid open for 15 to 20 mins after
