Water Maintenance

Nature 2


Start Up

Drain and refill your spa. Balance water, ph 7.4-7.8 Alk 80-100. Add 1 teaspoon of dichlor to spa per 250 gallons.


Every Day

Run spa according to recommendation supplied to you by the manufacturer of your spa.


Before or after each use

Add 1 tablespoon of potassium peroxymonosulfate (MPS) to spa per 250 gallons.
(Note: 1 tablespoon = 1 tablet = 3/4 ounce. A convenient way to insure proper MPS level is to use a Nature2 Spa Test Strip. If the Nature2Spa Test Strip indicates a low level of MPS, add 1 tablespoon of MPS to spa per 250 gallons and retest.


Once A Week

Add 3 tablespoons of potassium peroxymonosulfate to spa per 250 gallons. Check and adjust pH and total alkalinity. A convenient way to check pH and total, alkalinity levels is to use a Nature2 Spa Test Strip.


Every 4 Months

Drain and refill your spa.
Replace Nature2 purifier, repeat purifier start-up.


As Needed

If water looks hazy, shock treat with 1 teaspoon of dichlor per 250 gallons, and you can use sea klear clarifier.


The Nature2 Spa Purifier is not to be used with products containing bromine, sodium bromide or biguanides. If these products are being used, be sure to drain and refill spa with fresh water.


Bromine Spa

1. fill the spa and balance. If you have well water or know your water has metals then add a metal sequestrant at this point.
Adjust TA to 80-100 and Ph to between 7.4 - 7.8. If Ph is good, but Alk is a little off, its ok. Alk is the Ph's buffer, I can explain this to you if you request, as its a lot of information!

If your hardness is above 50 and you do not have a plaster/gunite spa, do not add calcium. If it is over 400 please give us a call.

2. Add 1/2 oz of sodium bromide per 100 gallons of water to create your bromide reserve in the water.

3. Shock the spa to 'activate' (oxidize) the sodium bromide into hypobromous acid (this is your 'bromine' sanitizer that you test for with your strips or test kit.) You can use MPS to shock, this tends to have less of a "smell" but chlorine works just as well if not better and is much less expensive. Uncover the spa and circulate until the bromine drops below 10 ppm before you use the spa.

4. Put in the floater with your bromine tabs (which usually contain BOTH bromine and chlorine to activate the bromine, btw) and adjust the floater to maintain your bromine at about 4-6 ppm. this can take a bit of trial and error. If your bromine is low, add small amounts of shock untill your reading gets to 4-6 ppm. It really only takes seconds for the chlorine to oxidize your bromide reserve into bromine sanitizer. If pH is not between 7.2 and 8.0 then you should adjust it before entering the spa and wait abot 30 minutes then retest it to make sure it is in the proper range. If both are off then adjust pH first then the bromine. If your bromine is always low open the floater a bit more. If high then close it down a bit. If it is above 10 then take out the floater and open the spa until the bromine level drops below 10 before entering the water and close the floater down a bit. Once you get the floater adjusted the bromne level will stay pretty constant and it becomes much easier! Remember to keep tablets in the floater at all times!

You are done!

Weekly test pH, Keep pH between 7.4 -7.8 and then when you have finished adjusting shock the spa with mps or chlorine just like when you added the sodium bromide but you do not need more sodium bromide

Every 3-4 months drain, refill, balance the water, add the sodium bromide, shock, and put the bromine tablets/floater back in.
Actually pretty easy!

Chlorine Recipe

Easy Start-Up Directions NOTE: Any time a chemical is added, make sure that the water is at least 80 degrees, the jets/pumps are on, and leave the lid in the open position for 30 minutes to an hour. Many chemicals use gallons as a dosage guideline. Having a spa care chart is a great way to keep track of how the usage affects the water quality and chemicals, and will provide a guide to help establish a regime.

1) Test the water. This provides an idea of the quality of water from the initial start up.

2) Add calcium and alkalinity increaser if needed. If calcium is at least 50ppm, its fine, unless you have a gunite/cement spa. If Ph is fine at this point, do not adjust the ALK as it affects the PH.

Note: Water from a well source may not need calcium or alkalinity at first, but will need one bottle of metal out.

3) Wait 1-2 hours for the alkalinity to dissolve properly (test again) then adjust ph up or down if needed.

4) Add Chlorine (in accordance with the directions on the bottle) to establish and maintain the recommended amount of chlorine. Chlorine is the sanitizer. It will need to be added frequently and directly relates to how much the spa is being used.

5) Shock (MPS chlorine free shock) assists in keeping the water clear. Add shock at start up and once or twice a week depending on usage. Continue to test the water regularly (minimum of once a week). Maintain the correct balance of alkalinity, PH and chlorine.

Keep the filters cleaned regularly and in accordance with the usage.

Drain and refill every 2-3 months or when CYA reading becomes high.
