What is the optimal pH for my pool or spa when using Orb-3 enzyme products? + -

The typical industry recommendation for pH range in pools & spas is 7.4 - 7.8. This is also a great range for the Orb-3 enzymes, so no special adjustment is required when using our enzymes.

Should I buy the ORIGINAL or NON-FOAMING version? + -

Most people prefer the NON-FOAMING. It is the newest formulation & works great. However, the ORIGINAL formula has been around for a long time & has many fans so we continue to make it available.

I put this in a little while ago & my water looks worse. What happened? + -

Orb-3 Spa Enzymes goes to work immediately breaking down organics - body oils, lotions, grease, etc.

Some of those organics are lurking in the plumbing of your spa/hot tub, collecting dirt and keeping it stuck to the walls of your piping.

When Orb-3 dissolves the grease, the dirt is let loose from the pipes & into the water.

Give it a little time - typically 24 hours or less - the filter & the enzymes will clean it up and then the water will be better than ever, the pipes will be clean, and the problem will not recur.

Can the Orb-3 enzyme products be used with DE filters? + -

Yes. Orb-3 enzyme products work very well with DE filtration media. The enzymes keep organics such as oil & grease from accumulating on the DE allowing it to filter as efficiently as possible.

Can I stop using sanitizer (chlorine, bromine, etc) in my pool or hot tub if I use Orb-3? + -

No, we do not recommend this approach.

However, since a secondary function of most sanitizers is to "burn off" the organics, many customers report that they use less sanitizer when using Orb-3 products.

Orb-3 products do not kill pathogens and consequently you need to continue using a sanitizer in order to provide safe water that meets health department standards.

The primary benefit to using enzymes is that they will reduce organics (lotions, body oils, urine, etc) in the water which will improve the clarity of the water, allowing it to sparkle & providing better visibility to the bottom. Enzymes also reduce scum lines & slimy films.

Are there any animal products in Orb-3 Products? + -

Orb-3 Pool & Spa products contain no animal product whatsoever. All items are either food-grade or GRAS and are plant derived, mineral based or synthesized. They are non-toxic when used as directed, and do not contain phosphates, sulfates, or paraben; and are gluten free as well.


Eco-friendly and cost effective, Orb-3 Spa Enzymes are a natural solution for your family's spa. By naturally removing organics from hot tubs and spas, Orb-3 Enzymes clean and freshen water making it healthy, clear, and sparkling. Orb-3 Spa Enzymes augments the natural decomposition of organic materials in spas while it helps stabilize pH levels to reduce skin & eye irritation, keep spa filters cleaner, decreases unpleasant chemical odors, and controls scum lines. You can rest assured that your loved ones will be able to enjoy a clean, healthy spa with help from Orb-3!

Totally compatible with whatever chemical spa treatments you might use, Orb-3 Spa Enzymes natural cleansing action washes away gunk and the slimy unmentionables in your water, allowing conventional sanitizers to work more effectively. Stop spending time and money on ordinary products that deliver ordinary results, and get the secret to crystal clear water with Orb-3 Spa Enzymes today!

Now available in the original formula or *new* non-foaming version! The non-foaming version offers the same great performance with a specialized non-foaming surfactant.

Used for 3 years in my Jacuzzi, no other products, no testing - perfect water!

I've had a Jacuzzi/SPA for many years, and dreaded the chore of testing & balancing the chemicals. I dreaded even more the headaches from the chlorine. The Orb-3 enzymes solved all my problems. I always look for the lowest hassle way of doing things, so I don't think I use it exactly as instructed, but it works for me amazingly. Here is a summary: 1. I dump some of the material in the Jacuzzi - I never measured it, but my guess is between 1/4 cup and 1 cup, and run the jets for 10-30 minutes. 2. I repeat step #1 whenever the water is less clear, starts smelling or any **** builds up. The frequency highly depends on my use, but probably about every few weeks. If you deal with chlorine or any old-school way of cleaning your water, this may sound far too good to be true. Well, this is my reality for a full 3 years, and probably a lifelong future. I am really sensitive to chlorine and toxins, and now my spa water feels like normal shower water - no irritation, no headaches. I come out fresh like from a shower. In terms of service, I called the company with questions, and the service was superb. So nice, so eager to help. Thank you! Gil

White Mold In Spa

I want you to know that your Orb-3 Spa Enzymes product was very effective in correcting the white mold problem in my spa. I have been a continuous Spa owner for the last 20 years and my experience tells me that you have a great product for stabilizing and maintaining water quality. My specific problem was that, although I had faithfully followed recommended maintenance for my Allure L700 Vita Spa, the spa developed a stubborn, white tissue-like mold in the lines. The problem occurred because of lack of consistent Spa use even though the L700 has automatic high and low speed cycles for circulating the water through all lines and pumps. Orb-3 Spa Enzymes cleared up a problem that shock and maintenance chemicals alone did not resolve. Thanks for helping me and the other Spa owners [and] for providing a quality product.
