I have an Intex above ground pool that did not get taken down from last year. I live in SD, but thankfully we had a very mild winter so it seems the pool lining is all in tact. The problem is that we didn't cover the pool either so any snow/water/bird poop/etc that did accumulate sat in the pool for months. We have pumped all of this water out and cleaned the empty pool with bleach, but it still smells like poop. How do we get rid of this? My fiance said that once we fill the pool we will put shock treatment in the water, but shouldn't we do something before we put the water in? I want to have as clean a pool as possible before we add the water...lots of people and kids swim in the pool and I want to have peace of mind that it's clean. Any suggestions?
