No nothing to worry about I have trees at the down hill side of pool and they cop heaps of chlorine water and are thriving.
The recommended safe level of chlorine in a spa is between 3-5 parts per million (ppm). Chlorine levels above 5 ppm can be irritating to the skin, eyes, and respiratory system. Excessive chlorine levels can also cause corrosion of equipment and damage to the spa surface.
If there is too much chlorine in your spa, you can dilute the water by adding more fresh water. Another option is to use a chlorine neutralizer to reduce the chlorine levels quickly. You can also leave the spa cover off for a few hours to allow the excess chlorine to dissipate.
Trichlor is a water sanitiserTrichlor is used in spa because it provides chlorine that disinfects the spa/spa. Trichlor has a content of 89-90% available chlorine. Trichlor is the least expensive substance that can be used to sanitize pools/spas.
You cannot "contaminate" a chlorine pool or spa with salt or vice versa. Chlorine starts as salt. Chlorine generators use salt to make chlorine. Therefore your "salt" spa is already a chlorine spa, you are just not putting chlorine tablets in it. It is a very common misconception that a salt system is some how different than a chlorine system. There are no "salt generators" and the salt does nothing other than allow a "chlorine generator" to produce chlorine. We get this question almost every day and it's generally because customers are "sold" not "told" about the product they purchased. If you were expecting anything other than purchasing a device that makes chlorine from salt, you will be disappointed. Pool & Spa
You need to have your check valve replaced.
To make a 20 ppm chlorine solution for a 250 gallon spa using liquid household bleach, you would need to add approximately 1.8 fluid ounces of 8.25% bleach to the spa water. This calculation assumes that the bleach is added to a freshly filled spa with no existing chlorine in the water. Be sure to test and adjust the chlorine levels accordingly before using the spa.
Pool chlorine is typically stronger and designed to treat larger bodies of water, such as swimming pools. Spa chlorine is milder and formulated for smaller bodies of water, like hot tubs or spas. It is important to use the correct type of chlorine for each specific application to ensure effectiveness and safety.
Cyanuric acid is generally called chlorine stabilizer and it is used to prevent the suns UV rays from eating up the chlorine in outdoor pools. Because most spa's are covered when not in use this is generally not a concern for spa or hot tub owners. If you do however have an outdoor uncovered spa and you wish to raise the CYA level you would simply visit your local pool supply store and purchase some chlorine stabilizer, just ask for cyanuric acid and they will know what to get you.
yes so long as you work out the right amount. Spas are a lot smaller then pools.
You are probably not going to remove the "stain" from the cover. It has been bleached of all pigment.
Chlorine, bromine, uv, ozone.
If you live near trees or places that have a large amount of snow fall, it may be necessary to own a spa cover. Given the recent dust storm in Phoenix, you may also want to avoid a muddy spa by owning a spa cover.
