Temperature, pH, stabilizer level and calcium concentration all have to be measured to make the proper adjustments to the pool chemistry. Measure the pool temperature and record. Divide the number of gallons in
The amount of bleach you add depends on the concentration of sodium hypochlorite in the product you use. Like most products, Clorox is a 5% solution, and the company recommends adding between 100 and 200 ounces per 10,000 gallons of pool water. That's a little less than two 121-ounce bo...

Incidents of viral outbreaks have increased at an alarming rate over the past decades. The most recent human coronavirus known as COVID-19 (SARS-CoV-2) has already spread around the world and shown R0 values from 2.2 to 2.68. However, the ratio between m
To use: Spray or wipe it on the surface, allowing it to remain wet for at least one minute before wiping. Will alcohol disinfect surfaces? Isopropyl alcohol is an effective disinfectant against many pathogens, including coronavirus, as long as the concentration is 70%. Most rubbing alcohols ...
When the Cas12a crRNA complex binds to the specific sequence, active Cas12a cleaves surrounding ssDNA, resulting in a fluorescence signal. Within 40 min, this test could identify low concentration (1.3 copies) of the N gene using real-time detection or visual method (Ding et al 2020). ...
