Hi, I just started renting a house that has a pool, and I've never had to take care of one before. I've been all over this site, read the pool school, but I would really like a step by step. I should probably also state that at present, the pool is being drained and will be refilled as fats as possible from the hose... there was an entire ecosystem of tadpoles, frogs, and several different kinds of bugs in the pool, which is why I drained it. I'm not even sure if the pump/filter is in good working order. My question is, after I drain and clean the pool, what is the step by step process I should go through to have the pool safe to swim in (hopefully by this weekend, 110 degrees here)?
