If you own a rental property, insurance on the rental is fully deductible as a business expense. Taking out liability insurance along with property insurance is a good idea, as it protects your assets if a tenant slips on a rickety step or says you evicted her illegally. You deduct rental expenses from rental income.
I added some pH minus, I think it's called muriatic acid, to lower my swimming pool pH level. I was wondering how long should I wait before I let my family go swimming after adding a pH minus or pool acid. Good question Larry. I would suggest a good 2 hour wait before you go swimming again.
You must wait for chlorine levels to drop after doing a pool shock. When doing a pool shock (superchlorinating the pool with concentrated chlorine), you should wait between eight and 36 hours before swimming in your pool.
