When should you put shock in your hot tub?

In essence, shocking your hot tub means adding a higher than usual dose of oxidiser chemicals to the water. This is also known as oxidising. We advise everyone to shock their water once a week to reduce bacteria and impurities. You can do this with one of two products; chlorine shock or non-chlorine shock.

How long after using shock can you use hot tub?

✔ Wait at least 20-30 minutes after shocking your spa to resume soaking into warmth. However, do this only if your water is tested and all levels are perfect! ✔ The sun can burn off chlorine, always shock your spa in the early morning hours or in the evening!

There is no need to shock a hot tub after refilling, even if tablets are used as sanitizer since the water is fresh and does not yet contain contaminants or sanitizer that has been depleted.

How long does it take for shock to work?

Heavy shocking with granular chlorine will generally require 24-48 hours before the chlorine level has dropped to safe swimming levels (below 5 ppm). Lithium and Non-Chlorine shock labels typically allow immediate swimming, but check the package label, to be sure.

What happens if you go in a pool that was just shocked?

In terms of swimming in a pool that has been recently shocked, you may be exposing yourself to the risk of skin and eye irritation. If this happens then rinse thoroughly with clean water for several minutes (source).

Should I brush pool before shocking?

Before you start pouring shock in the pool, the first step is to brush the sides and floor of your pool to loosen all the algae. Doing this breaks the skin and allows the pool shock to more easily kill the algae. Once you've done this, it is important to make sure you have the proper pH level in your water.

To dose your hot tub ready for bather use, we advise using chlorine or bromine granules rather than tablets, which should be added only when your Hot Tubs pump is running. It is important to ensure your spa water is at a normal level of 3-5 parts per million (ppm) for free chlorine and 4-6 PPM for bromine before use.

How do you shock a hot tub for the first time?

How soon can you go in spa after adding chlorine?

Again, as a general rule of thumb, people should wait at least 30 minutes after adding chlorine before getting in the hot tub. Those who use bromine might have to wait a little while longer. Make sure the hot tub cover is off, allowing chemical vapors to escape.

What temperature should I leave my hot tub on overnight?

Knowing that hot tub water heats up around three to six degrees per hour, keeping it as low as 10° less can still be fine. At most, it will take about 3 hours to get back to normal when you're ready for it. But if you find your hot tub heats slower, or you don't like waiting, keep it at 5 degrees less instead.

What chemicals go in hot tub first?

The chemicals you will need to start your hot tub include a pH increaser, pH decreaser, calcium hardness, a metal removal (if using water from rainwater tanks or bore) and a sanitiser.

How does spa shock work?

How Does it Work? The main purpose of spa shock is to break-down organic waste contaminants which cause bad odors and cloudy or foamy hot tub water. It does this by oxidizing the water, which is the process of rapidly removing the outer electrons from contaminants in the water that the spa shock comes in contact with.

How much shock should I put in my hot tub?

For a 300 gallon spa, 0.7 oz of Chlorine Granules shaken over the water surface, will raise the chlorine level up to about 10 ppm. This should be done with a balanced pH (in the low range of 7.2-7.4), and with the circulation pump running on high to help distribute the shock quickly.

What order do you adjust spa chemicals?

Mix the chemicals in warm water first to dilute the granules, then tip evenly around the deepest part of the hot tub. If it is above the OK range, then you risk scale forming and cloudy water. It is difficult to lower Calcium Hardness, so we suggest the use of a Scale Inhibitor as a precaution.

Can I use my hot tub without chemicals?

It's not advisable to use a hot tub without any chemicals. Without chemicals, the hot tub becomes unsafe and can cause hot tub rash, and the water becomes host to harmful microorganisms. Over time, the contaminants in the water also have an adverse effect on the hot tub's equipment.

How soon after shocking pool can I swim?

And how long do you have to wait before you can swim? You should wait one hour per pound of shock product added, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool.
