Just let it disipate.
The same as you would a fresh water spa.
If you leave them open for a very long time or add other chemicals to it then yes they can sometimes go bad but most spa chemicals are good

The types of chemicals needed to maintain a good balance in your pool or spa include chemical and non-chemical sanitizers, shocks, acids and alkalis, and total dissolved solids.
A small of amount of muriatic acid
It will take two steps to take care of this situation. First: Use acid to lower the alkalinity to the desired level. This will lower the pH also...so: Second: Add pH up to raise the pH. This will not raise the alkalinity. Kind of a pain. Try using soft water to fill if you're just filling a spa. A pool needs too much water, so it'll take two steps. If you're starting up a spa make sure to wait long enough between adding the chemicals and taking the next test, to allow the chemical reaction to occur. Run the pump(s) (no Air) for 30 minutes then wait at least three hours before the next test.
You may want to add muriatic acid in small amounts more frequently - say every 20 minutes. The alkalinity will take care of itself. Be sure of your test results. You may have old test solutions or an old test kit. If you have access to digital testing equipment that may be more accurate. The addition of baking soda in small amounts will raise the alkalinity. Monitor it about 20 min. after application with a good test kit. To keep your pH from rising too much add the acid as above. Keep this up until the alkalinity is close to the minimum rating for alk. Test again the next day to see of it has stabilized. If not continue the application of baking soda. This may take from hours to days to correct. If you have a small body of water, like a spa, it is easier, quicker to change the water.
If I owned a spa/Winery in Tuscany Italy....How much would I make a year?
Various options are available with a Spa Management degree. You can focus on Spa Design, be a personal services consultant, be a general spa manager, do spa marketing and promotions and much more.
Bathers contribute body oils to the spa. Foaming is usually caused by a reaction of body oils and cosmetic residues with the alkalinity of the water. This can lead to the formation of "soaps" and foamy water. The foam can be eliminated by using Anti-foam and enzyme products periodically.
The price of a spa pump will vary depending on brand, size and power required for the spa. Generally, spa pumps will cost in the region of å£40 or $70.
it depends whether he is good at his job, bad at his job and where he has his spa!
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.
I have a 2000 gals in-ground spa and I find that I have to put some baking soda in the water to adjust the alkalinity level to 80-120, according to the test kit. When my spa's water alkalinity starts dropping down to 70-80, then I spkrinkle in about 4 oz. of baking soda. That always takes my alkalinity reading up to about 100, which is perfect for my size spa. Since you have 1000 gals, I would go ahead an sprinkle in 2-3 oz. of baking soda. Circulate the pool water for about 30 minutes and recheck your alkalinity. Should be fine at that point.
Tell them you will do a much needed task for the family, and ask for your reward to be a trip to the spa.
