Hot Tub Spring Cleaning

Spring has Sprung

Spring has sprung once again and it’s 2019!  Cooler nights and warmer days provide perfect hot tub weather.  Crank the spa up to 105 and enjoy.

Here are a few things to check and be sure the spa is ready for the season.

Hot Tub Spring Cleaning

  1. Clean or replace the spa filter

Getting a new cartridge is easy at Spa Filters Canada.  Look for the filter part number stamped on the filter end cap and enter it into the search box. We find you the best prices in Canada on replacement filters.  Buy 2 replacement cartridge filters in Canada and have an extra one to rotate in while the other one is being cleaned because most hot tub manufacturers warn of never running the spa without a filter.

If the existing filter cartridge is less than a year old, then proceed with cleaning it. If the pores are not looking too great, treat your cartridge filter to an overnight filter bath. You may need the overnight filter soak.  Put it in a bucket of water per dosage on the bottle.  Soaking the cartridge overnight allows the pores to become unclogged as oils and scum are eaten away by the solution in the bucket bath and the next day, out comes a nice clean, unclogged filter for reuse.

     2. Clean the cover

If the core is heavy or waterlogged, you will need to unzip the cover and remove the inside foam core to let it dry out completely. You will also need to locate the tear(s) in the vapor barrier and seal it up with a patch kit such as Tear-Aid.

If the cover core is too far gone, the entire spa cover will need to be replaced.


   3. Check hot tub components and operation

Power the spa down by shutting off the breaker and remove the service panel to have a look inside.  Did anyone decide to make this their home over the winter? Are there any obvious signs of chewed up wires or other critters?  Clean out those spider webs and other debris so nothing gets in the way of pump operation or future servicing needs.  Once the inside looks fine, close the cabinet back up (unless you need to access the spa drain from inside the cabinet).

   4. Change the water

If the hot tub water has not been changed in the last 3 months, it’s time to get a fresh start in the spring.  TDS or total dissolved solids creep higher when using chemicals to treat spa water. At one point it is best to change and start fresh.   Since the water has probably not been drained recently with all the snow, it is time to change it.

See our tips on draining a hot tub.

Use a pre-filter to filter out the hose water and really get a fresh start. The pre-filter attaches to a garden hose and filters out metals and contaminants so you don’t have to battle them later inside the spa.

Fill the spa from the filter area/compartment (the filter is still removed for cleaning while you are refilling the spa). This way air pockets can be avoided that may give you problems on startup. 

Once the shell is wiped down and the spa is full of fresh clean water, insert a new or cleaned filter and start ‘er up.

   5.  Chemical Balance – check water with a test kit or test strips.

Get the pH and sanitizer levels in order when the spa reaches the set temperature.  It is never too early to fill up the chemical dispenser with bromine or chlorine pucks though. When using bromine instead of chlorine, add some sodium bromide to the water to establish an initial reserve since bromine takes longer than chlorine to get to the correct levels from the tablet form (you may otherwise need to wait a day or two until you can use the spa).

Enjoy beautiful spring evenings in the hot tub!
