Filling & Draining

  1. Fill Spa & Hot tub to the correct water level (at least halfway up the top skimmer/filter opening)
  2. Test pH and Alkalinity using Test Strips at least weekly. pH should be between 7.2 to 7.8; total alkalinity should be between 80 to 140 ppm; water/calcium hardness should be between 200 to 400ppm. If not, make the needed adjustments using pH Increaser, pH Decreaser & Alkalinity Increaser, and Calcium Increaser accordingly
  3. Use Stain & Scale to prevent & remove mineral scale buildup and to protect your spa components
  4. Add Chlorinating Granules to dissolve contaminants in your water quickly. If your spa is not Chlorine compatible, try our Bromine Spa Starter Kit


Maintain the recommended chlorine level at all times. Aquadoc Chlorinating Granules recommends maintaining 3-5ppm of FAC (free available chlorine) while the hot tub/spa is in use. Test the chlorine level regularly, especially before and after each use. Add Chlorinating Granules as needed to achieve proper levels


  1. Test water using Test Strips; adjust total alkalinity, pH levels, and calcium hardness using pH Increaser, pH Decreaser, Alkalinity Increaser & Calcium Increaser accordingly
  2. Add Chlorinating Granules when necessary
  3. Add Water Clarifier to defend against cloudy water
  4. Add Spa Defoamer to get rid of foam
  5. Add Chlorine Free Shock after every use to quickly oxidize contaminants

Important! Circulate your Spa or Hot tub water for at least a few minutes after any chemical addition and before adding another product. Please follow the instructions on the container of each chemical in the kit carefully for maximum results and safety!

All The Chemicals You Need To Keep Your Spa's Water Properly Balanced!

If you already own a spa, or if you just purchased one, you are going to need some starter chemicals to get your water balanced. This kit includes everything you'll need to do just that. Once you run out of one of the chemicals, simply replace that particular bottle and continue keeping one of each in your home's stock. Highly recommended, especially for Amazon's low listed selling price.


Everything you need!

I was so pleased to find this Starter kit! Last year we had to buy every thing separately and let me tell you, you are saving not only time but also money buying it all together like this. It's so easy to use and you've got it all on hand. The products work quickly and accurately. I'll never go back to buying as needed, because at some point you will need everything.


Perfect starter kit

Just set up my hot tub yesterday and used some of these to get things started. I'm a pool and hot tub owner so I am familiar with chemicals.These dissolved just like they should and I didn't have any issues.This kit has about everything you need for your hot tub. Can't think of what might be missing.Overall, seems good.

Get started with everything you'll need

Starter set of chemicals has everything you'll need to get started with your hut tub. Using chemicals in a Coleman inflatable SaluSpa and this is our first hot tub. The directions are very clear and specify how much product should be used based on gallons of water or water readings from the strips. We most often use the ph decreaser, water clarifier, water defoamer, and shock. Also usimng the test strips. Chemicals do what they are supposed to do, although the ph decreaser takes more chemical than suggested in the directions. Although we're not likely to use the other products regularly, it's nice to have them on hand should we need them. Now that we've had a great start with our hot tub, we know which chemicals we'll need to buy in the future.
