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.
It depends on your 'danger' level. Any amount of chlorine can be dangerous. It only takes a few drops in a gallon of water to disinfect it (kill every living thing in there) after only a few minutes. Chlorine is classified as a toxin, yet it is put in our drinking water and in pools and used in spas. For a normal sized spa, I would never pour more than a cup of chlorine into the spa. 10 ppm is considered the max. If your spa is green and you are not going to use it then feel free to pour 2 or more cups in it. You're better off draining it at this point. To prevent chlorine breakdown, it is recommended that you add stabilizer and its level will depend on how big your spa is. Chlorine is dangerous because it can damage liners and upset water balance. I suggest that you use 2 ppm of chlorine or more then shock your water for it will prevent the bad odor.
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
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.
You need to have your check valve replaced.
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.
You are probably not going to remove the "stain" from the cover. It has been bleached of all pigment.
yes so long as you work out the right amount. Spas are a lot smaller then pools.
Chlorine, bromine, uv, ozone.
There is no direct conversion between liquid chlorine and chlorine tablets because they come in different forms and concentrations. It's best to follow the manufacturer's instructions on how much liquid chlorine is needed to achieve the same sanitation level as a 3-inch chlorine tablet in your specific pool or spa.
