The 
"DEALER"When buying a Hot Tub the 
DEALER can make all the difference.
After the Sale you will need advice on how to treat your water to get the right balance.  
Your 
Dealer should be able to test your water and tell you exactly what chemicals and proportions you need to properly balance your water. 
You should check your water yourself daily for Ph and Sanitizer levels, (especially if you are new at it or your tub has had a heavy bather load), and have your water checked by taking a water sample to your 
Dealer monthly.
This is a service that is available to you by your 
Dealer free of charge.  
(At least it is with Beachcomber Dealers.)This is one reason it is nice to have a 
Dealer close by.
I have no idea how people who buy hot tubs from Big Box Retailers or off the Internet, test their water for hardness and alkalinity without the help of the sophisticated testing equipment that the 
Dealer has.
I cannot 
stress how important it is to keep your water correctly balanced.  
Water that does not maintain the correct hardness and alkalinity can seriously damage your heater and hot tub and may even invalidate your warranty.  Of course the other reason is that having the correct amount of sanitizer is critically important to your health.
Note: Do not rely on an Ozinator alone.  Some sanitizer is always needed to maintain safe water.  The advantage of ozination is that less (chemical) that is sanitizer (chlorine or bromine), is needed to handle the bacterial load.
Most test kits only test for Ph and Sanitizer level 
not Alkailinity and Water hardness (Calcium), never mind TDS (total dissolved solids}, iron, copper, clarity and algae.
If you have installation questions, your 
Dealer should be able to advise you.  ie:  Foundation, electrical requirements, wire sizing, amperage of the GFI, and delivery.
Delivery;   It is best to contract the 
Dealer to deliver and set up..  Hot Tubs weigh between 500 to 800 lbs.  If there is any damage to the Hot Tub, it will be his problem, not yours.  There can be a real challenge in getting your tub to where you want it.  It may involve a crane or the removal of a fence or other obstacles.
Electrical:  Generally it is best to have your Electrician wire and connect your Hot Tub after installation so that he knows the exact location to wire to.  You may also want a 120 V GFI outlet to run peripherals such as a stereo or TV.
Start up can sometimes be problematic and it is nice to rely on your 
Dealer for information and help.  The 
Dealer should come out to advise you on water balancing and general operating questions.
Warranty Service; Your 
Dealer should be there for you for the entire warranty period and long after.
Tip:  After you become familiar with water care, buy your chemicals in the largest sizes available.  It is generally cheaper to buy in large sizes.
This all adds up to 
peace of mind in the Total Ownership Equation of owning and operating a Spa.
Happy Tubbing,Regards
