We bought a summer escapes 10x10 inflatable ring pool and filled it seven days ago. Two days ago I started noticing an odd odour on my daughter and tonight when she got out it was so strong it made me nauseous. We havent put any chemicals in the pool...we have just been using the filter as the water has been clean. Any ideas about what this is and if I should be worried for her health? Her bathing suitstill smells like it after i washed it? Kinda smells like poo??
