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.
5 - Low Cyanuric Acid Levels. If the cyanuric acid levels in the stabilizer are low, the chlorine will not remain in the pool for long. If the pool is being used simultaneously, the chlorine may be used up in a matter of minutes. Most manufacturers recommend 80 ppm of cyanuric acid for salt water pools.
