You are probably not going to remove the "stain" from the cover. It has been bleached of all pigment.
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.
A spa cover can support on average up to 300 pounds. However, I would not recommend testing this, as your results could clearly be negative. If you get snow or rain on your spa cover it should be fine, but if there gets to be a huge bowl in it, you should make sure to remove it so as not to rip the cover.
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
The blue/green stain is copper from your heater. Your pH and alkalinity are too low. You have to call someone (with experience) to drain and do a light acid wash to remove. Test water more frequently and adjust as needed to avoid same situation. Your spa will only handle a few acid washes before you have to re plaster. Your heater will not tolerate low or high pH.
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.
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.
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.
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.
Yes, spa bromine can tarnish silver. Bromine is a reactive element that can cause silver to tarnish and corrode over time. It is best to remove silver jewelry before using spa products containing bromine to prevent damage.
