Can You Use Pool Chlorine in a Hot Tub
Welcome back spa and hot tub enthusiasts! We take a shocking topic for discussion today, How to Shock a Spa or Hot Tub.
The term "shock" is something of a misnomer, although you lot may envision the oxidation process as an lightning bolt ripping through the water.
Shocking your spa effectively, for the right reasons, and without detrimental side furnishings, is the purpose of today'due south lecture.
Don your lab coat and your protective eye wear as we begin today's lab session to improve understand oxidation of hot tub contaminants.
What really happens when you shock a spa? Oxidation is the process of a particle losing electrons when it encounters a disinfectant.
In the case of granular chlorine or non-chlorine oxidizer – spa shocks, the oxidizer rapidly steals the outer electrons of contaminants it comes in contact with. The loss of these electrons makes a contaminant vulnerable to set on at a cellular level which quickly destroys the molecule.
Reasons for Shocking a Spa or Hot Tub
There are merely iv valid reasons for shocking your spa or hot tub. Information technology's not necessary to shock the spa every time yous utilise it and perhaps non even weekly. Shock your spa for these 4 reasons:
- To remove bromamines or chloramines in the spa. Using a DPD test kit, you can test for the level of combined chlorine or bromine. Calculation an oxidizer in the amount equal to 10x the level of combined sanitizer will pause autonomously these bonds and brand sanitation more efficient.
- To remove organic contaminants in the spa. When 3 or 4 users jump into a hot spa, the level of contaminants spikes to a level many times higher than your sanitizer can manage. Add an oxidizer afterwards spa employ to restore sanitary spa water, by breaking down bather waste product.
- To reactivate bromides in your spa h2o. For a bromine spa, using an oxidizer weekly helps maintain the bromine level in your spa water. Activating bromide ions with spa shock converts them to hypobromous acid, the killing form of bromine. More on edifice a Bromine Bank here.
- To kill bacteria. Remember that non-chlorine shock is not classified as a disinfectant similar chlorine or bromine, but is useful simply as an oxidizer. Employ chlorine spa daze to kill leaner or algae. Y'all may run across it, or just doubtable it, or you may find the chlorine or bromine level has fallen to zero; shock to heighten levels fast.
Preparing to Shock a Spa or Hot Tub
The almost of import thing to do in preparation for shocking the spa water is to first test and arrange the pH level to the range of 7.two-7.6. Oxidizers work best in a low pH environment, and the efficacy of your spa shock is twice every bit great at a pH of 7.v than it is at a pH of 8.0. Cheque to be sure that your pH is non too loftier earlier shocking.
The second most of import affair is to remove your spa cover, spa blanket and spa users earlier shocking the hot tub. Especially during the beginning 20 minutes, your spa surface needs to exist aerated to facilitate the exchange of electrons and gassing off of byproducts formed during oxidation. Spa cover materials and components can be damaged by the off-gassing chemicals.
The third nigh important thing is calm water – don't turn on the blower but practise run the apportionment pump when you shock the spa. Too much agitation tin can prematurely gas off potent oxidants. If you lot notice undissolved granules on the lesser withal, yous can utilize a castor or net to stir them effectually, but don't vacuum them upwardly.
And then to summarize preparing to stupor a hot tub:
- Lower pH level to between 7.ii-seven.half dozen before shocking
- Remove spa cover, spa blanket and spa users
- Calm water, keep jets on depression and blower off
Shocking a Spa or Hot Tub
When shocking your hot tub, pay attention to a few things. Specifically, exist cautious when using spa daze, oxidizers tin can be unsafe when misused or mishandled.
- Read the Label – dissimilar oxidizers accept varying strengths. Be careful not to overdose or underdose your spa shock handling.
- Measure your spa shock – dosing is so of import. If you are 1/2 of an ounce off, you can underdose or overdose your spa.
- Add Advisedly – loftier winds can blow spa stupor right in your face. Gently pour it over the surface and wash away any spills right away. Go along out of the reach of children.
Shock Before or After using the Spa?
I know people who exercise it before or subsequently, and some who daze both before, and after using the spa. If you are confident of the water balance and condition before utilise, in that location may exist no demand to shock before using the spa. I almost always shock my tub after a session.
On the other paw, if your spa water turns dull and cloudy after use, or after use your sanitizer level is zero, and pH is pummeled, you may desire to preemptively shock to heave levels. This is helpful for small spa filters that are overwhelmed with several spa users.
How long to wait after shocking a spa, before y'all can get in? I knew that question was coming! Consult your label, only near spa oxidizers demand but 5 minutes to fully deliquesce, disperse and to complete oxidation.
Which Spa Shock is Best?
Nosotros accept a large variety of spa shock that tin be used for oxidation. Cull one you like and get on with it!
Y'all tin apply chlorinated spa shock similar Spa 56 – very popular, or you lot tin use non-chlorine shocks like SeaKlear Spa Pods, or Leisure Time Renew, tabs or granular.
Use an oxidizer specifically labeled for use with spas and hot tubs. Do not apply pool daze in your spa. It is easy to overdose, and may contain other chemicals not needed in a spa or hot tub. The i lb. numberless are a safety hazard if not used all at once, and react with moisture, bugs or debris. They likewise spill easily, if non carefully resealed.
The most economical shock? Our own Spa Care spa stupor. Well-nigh value, pound per pound, and only as strong. And you can use the spa virtually immediately.
Remember my cautions above when using spa shock, because – Oxidants Happen!
