We ave owned a few intex easy set pools through the last few years. This is my second year with this specific pool. We didnt cover it all winter, just drained it. Today we flipped it over and got the nasty water out. I put bleach in and scrubbed the liner as we began filling it and smoothing it out. Ive got a good test kit and the basic chemicals. We use our pool A LOT (we are a family of 8!) and it rains A LOT. Plus, in the past I dont think we ever used stabilizer so we never kept a steady chlorine level. So, here I am. I have taken college level chemistry and I am a Nursing major so I get the acid/base balance stuff but still feel unsure if I should treat this size of a pool as a seasonal or regular pool (since its 5,500 at 80% capacity)
