How often you shock spa water depends on the sanitizer used and the bather load. If you are using chlorine or bromine tablets, it is recommended that you shock at least one time per week. It may be necessary to shock more often if the bather load is heavy or the water is cloudy.

Yes you should shock the water after you've filled the spa and removed the hardness from the water, and before using PristineBlue, using a non-chlorine shock. PristinePower, supplied in the starter kit, is best. When using PristineBlue, you should also shock water fortnightly with PristinePower to destroy organic wastes, body fats and oils that the filter is unable to remove. This will help to keep the water crystal clear and ensure that you use less of the PristineBlue liquid.

YES! We have extensively studied the length of the heat shock and found the heat shock time is necessary to obtain a high transformation efficiency. A heat shock of 5 min will not give rise to optimal transformation efficiency using this Kit.FAQ Some publications have used 10% volume of ethanol or DMSO or a specific concentration of bme or DTT in the transformation reaction.

Although Free is persistent at controlling bacteria, it is important to remember that a spa is a small body of water. So, continual use means bathers will deposit large amounts of dirt, perspiration, body oils, deodorant, make-up and other contaminants into a relatively small volume of water. If your spa is used heavily (approximately two people, three times a week, a half hour at a time) we recommend that you change your water every 60 days.

Sit down, if you’re not already sitting or lying down! If the first shock doesn’t correct the problem you may receive another. You want to avoid further injury as you may fall onto something. Your doctor should have given you instructions on how to proceed. Generally, if you have received multiple shocks they will want to see you immediately. If you have a single shock and you feel fine, you should still give your EP office a call.

To begin with, it should be noted that "Northman" is a frequent posted to our message board. The following is his personal recommendation for water care. The information below is the result of over 10 years experience as a spa owner and a desire to find an effective method of spa sanitation which is simple but effective and leaves very little if any chemical odor.

Use your garden hose to fill the spa. It is best to run the hose first for a few minutes to flush out any stagnant water before filling the spa. There is no special plumbing required for a Relax Spa.

When you test a spring to find out its spring rate you are basically compressing it on top of a set of scales. The very nature of what we are doing here is getting a reading of how much tension this spring has, its also telling us that its transferring 176 lb of force to whatever is on the other side of the spring, in this case scales, in the case of real world installation its the buggy chassis.

Probably (this is in reference to the underwater temperature readings we provide on the ReefCam pages). The underwater temperature probe we use is reasonably accurate, but we've found that water temperatures in the shallows can vary by several degrees Fahrenheit. Use the number as a relative measure and you'll be fine. Water temperatures at diving depths on Bonaire range from about 77 to 87 degrees Fahrenheit.

Regular testing of your hot tub's water prevents problems which can cause your spa being shut down & being unhealthy. Testing also prevents long-term problems such as corrosion of filters & metal pool accessories & parts. Prevention of scaling of a spa's heater is another long-term need. We didn't even talk about odors & germs.

Yes it is vitally important to drain the spa water after 8 to 12 weeks depending on usage use. Impurities can build up and the only effective way to remove them is to drain the water and replenish.

No. And yes. Fresh clean water is what you want in your tub. Warm water in a hot tub will get unsanitary quickly unless you are proactive. There are a lot of so-called "non-chemical" sanitation products that are mostly wishful thinking. To have safe water without being a chemist, we recommend using the "bank and activate" sodium bromide salt approach. This is a very simple, safe, and vigorous way to keep your tub water safe for your family.

All public swimming pools or spas are required to have a permit to operate issued by the Environmental Management Department, Environmental Health Division. Private pools and spas are those which are intended for non-commercial use and are not used by more than three owner families and their guests. Private pools meeting this requirement do not require a permit to operate from our Department.

Non-chlorine shock for pools is not buffered and may effect the overall water chemical balance of the spa water. It is best that you use a non-chlorine shock, such as Leisure Time Renew, designed specifically for spas. This will help reduce the need for extra chemical treatment to keep pH in the proper range.

Because of the efficiency of Nature2, super-oxidation is needed less often. You only need to super-oxidize if the pool becomes dull or cloudy. The start-up of each new cartridge requires an initial shock with chlorine. Follow chlorine manufacturer's label/instruction to super-oxidize. Please refer to the appropriate literature for information on using Nature2 in portable spas. For more information call Zodiac Pool Care at 1-800-822-7933.

Because of the chemicals that most people put in their spa baths we do not recommend that you use the Q2 Water Energy System in the spa. These chemicals are the same principle of foreign additives to the water, they are bad for the unit and bad for you. Another reason is that the current from the air jets could damage the unit. In addition, the fact that the water in spa baths is not changed after every bath does not make this a very good choice for treatment with the Q2 Water Energy System.

This is dependant on how much the spa is used but it is best to think in terms of about 4 to 6 weeks, for details see our booklet Spa Care Made Simple.

Turn the spa off at its power supply, open the access door on the side of the spa, connect your hose pipe to the drain valve and open the drain tap. Alternatively some owners buy a small submersible pump to empty the water faster.

Anaphylactic shock is a life-threatening allergic reaction. Symptoms can include swelling in the mouth and throat, wheezing, difficulty breathing, hives, fainting, and drop in blood pressure. This is caused by the cells in the body releasing large amounts of histamines into the blood. This type of reaction is rare and can be caused by allergic reactions to foods, medications, or insect stings. Anaphylactic shock is a medical emergency and can cause death if not treated immediately.
