## Questions & Answers

**Q: Is this the oxidizer (step 2) or sanitizer (step 3)?**
A: The oxidizer IS Step #2. Sanitizer IS Step#3. Do not Increase/Decrease recommended dosage. Love the way this product works. Keeps water clear as a bell. Very “skin” friendly. Enjoy.

**Q: How long will this product last?**
A: There is a “Start-up” procedure (3 oz per 150 gallons) and there is a “Weekly” procedure (1-3 oz per 150 gallons depending on spa usage). So, it depends on how many gallons in your jacuzzi and how often you use it.

**Q: Is this the same as Baquaspa oxidizer?**
A: Correct-replaces the Baqua Spa Oxidizer product that has been discontinued, but same 7.5% hydrogen peroxide and usage steps.  Made by the same manufacturer and basically a refreshed branding, is my understanding.

**Q: It says this 7.5%h2o2 & water. can i just mix 7.5 oz. of  h2o2 with 92.5 oz. of water and replicate this product?**
A: The container is 32 oz.  7.5% of 32 oz. is 2.4 oz.  You'd need to mix 29.6 oz. H2O with 2.4 oz. H2O2 to make the full 32 oz.  I'm not sure if the H2O is just ordinary water or distilled water.  Try it and see.  It's definitely a lot cheaper.

### ⭐⭐⭐⭐⭐ great product for water clarity
*by R***D on September 10, 2025*

This is a great alternative to the high smell and chemicals of chlorine and bromide. It does a great job and does not smell or leave any kind of stains or discoloration on materials. The water is always very clear.

### ⭐⭐⭐⭐⭐ Works well
*by A***R on June 6, 2025*

Great product. Arrived quickly.

### ⭐⭐⭐⭐⭐ Not as concentrated but probably better formula
*by T***Y on August 31, 2023*

In the past I had used a powdered shock oxidizer formula but we have been noticing something in it goes airborne and makes us cough in the jacuzzi, this oxidizer in this liquid form seems to function just as well however you need to use a lot more of it, the price point is pretty good with that in consideration though they recommend 1.5 to 3 oz per 125 gallons so it's not as concentrated as some powder formulas, but we have been noticing a better water quality and this formula is not making us cough when the Jets run so I feel a lot better about this formula than the one we had been using in the past.
