i have a 16x48 intex above ground pool. the pool came with a filter but i purchased a new one (next size up from the one that came with pool). i left on a trip for 5 days & came back to a cloudy/mint green color pool. my hardness is 100, total chlorine 3, free chlorine 3, bromamine 6, ph 6.8, alkalinity between 40 & 120, stabilizer 50. do i need to shock the pool or get my ph level up first? ive taken my chlorine floater out & its too cloudy for me to see if it needs to be vacuumed. PLEASE HELP!!!!!
