Spa Water Care: Purge, Drain & Refill

Probably the most important aspect of Spa & Hot tub care

 

Draining your spa or hot tub is a very important factor in caring  for your spa, the spa's components & more importantly, the people using the spa.


Draining & refilling too often is a waste of your time & the valuable resource of water.  Not draining & refilling often enough will lead to hot water care problems which can lead to excessive bacterial growth which can lead  to skin rashes, possible ear infections, "hot tub lung" & other physical health related conditions. 


Purging, draining & refilling helps to rid your spa of unwanted mold, bacteria & biofilms.


A good tell tale sign that a spa's water needs to be changed is the water is very foamy and the anti-foam you're adding has minimal or no effect and/or the water doesn't smell clean.  


When in doubt, drain  it out.  It may seem like a pain, but your health & safety is our first concern.

How often to Purge, Drain & Refill

Timing is everything...

The formula is pretty simple. Take the  number of gallons in the spa divided by the average daily bather load then divide that number by 3 to get your answer.


First example: a spa or hot tub with 300  gallons of water that is used by 2 people twice each day 5 - 7days (equals  bather load of 4).  300 ÷ 4 = 75 ÷ 3 = 25 days or about once per month.


Second example: a spa or hot tub with 300  gallons of water that is used by 2 people once each day 5 - 7days (equals bather load of 2).   300 ÷ 2 = 150 ÷ 3 = 50 days or about once every 2 months.


Why so often? Each person using a spa or hot  tub "relieves" themselves of about 1 pint (16 oz) of body fluids per 20 minute  soak (sorry to be graphic). Now multiply that by more than one person - as in a party - and the body fluids add up!


This formula is not concrete, HOWEVER it is a good guideline to follow.  Depending on how much the spa is used directly  determines how often it needs to be drained & refilled.  It may seem like a  lot but consider this:  if you were soaking in a bathtub every night, how often would you drain & refill the tub?  Every time you used it, right?  Right!


Remember that most commercial spas need to drain & refill their spas at least once per week!  Or they should!

3 Easy Steps to a Clean Spa or Hot Tub

EVEN IF YOUR SPA IS BRAND NEW, FOLLOW THESE INSTRUCTIONS!

Many  spa & hot tub water problems start from a lack of proper  maintenance; especially drain & refilling. But it's just a little  more than that. We are answering a LOT of questions dealing with slime,  spa mold (WWM) & biofilms lately. 

Keep in mind that these problems are preventable.  Also keep in mind that normal maintenance including shocking & water balance will have almost no effect. The fact is shocking with tons of  chlorine, bromine or hydrogen peroxide WILL NOT do a good job killing  it, never mind removing it.
 

WWM grows & thrives on an underlying "bed" of bio-film. And even  bio-film is VERY chlorine/bromine resistant. The only way to deal with  the WWM is to use a product such as Spa Purge (good) or Swirl Away or Spa System Flush or SpaBoss Whirlpool Rinse  (all of these are OK) or AquaFinesse Spa Clean Tablet (better) or Hot Tub Serum Total Cleanse (BEST - 10 times better & faster)  to attack & remove the biofilm. Here's some further information regarding biofilms & white water mold


Follow these 3 Steps whenever you Drain & Refill your spa:

  1. Add the Spa Purge, Swirl Away, AquaFinesse Spa  Clean Tablets or Whirlpool Rinse to the spa. Allow to run overnight,  about 12 hours or so. These products will aid in removing the existing  bio film. Don't be surprised if the water gets NASTY looking.   

    If using Hot Tub Serum Total Cleanse, it will work remarkably quickly & thoroughly. Allow   it to run for 20 - 30 minutes, then continue.
     
  2. Drain & physically clean all fittings, pillows, skimmer & filter areas, etc.  Be sure to chemically clean the filter cartridge on a monthly basis.
     
  3. Refill the spa. 

In  a bad or serious case of WWM, it may be a good idea to repeat the procedure.  That way you can start off clean. Biofilms will  re-grow, so whenever you drain & refill the spa, you'll need to purge the  plumbing lines where all of that stuff grows.


There is no real way to  prevent biofilm growth, unless you are supplementing the spa care with  AquaFinesse or Hot Tub Serum. These products have good field proof of preventing & removing bio-films. 


Chlorine, bromine will both be absorbed by the biofilms.  Ionizers like Spa Frog or Nature 2 have no effect. Biguanides like Baqua Spa,  Soft Soak or Leisure Time Free will only "adhere" to the bio-film.
 

There is no easy fix and you've got to be aggressive against it.
