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.
Add the acid to the bucket and pour it slowly around the deep end of the pool. If you are adding a large quantity of acid, do it in stages - DON'T add large amounts of acid to the pool at one time. Allow the pump to circulate the water for at least 4 hours and then test the pH again. A pH reading of 7.0-7.6 is required, with 7.2 being the ideal level. If you add too much acid to the pool at one time, you risk etching the walls, corroding the pipes and pump fittings and you lower the total alkalinity of the water.
