Hi so iam a new pool owner. We opened our pool and had it almost clear and my husband and daughter swam in it. That night we had a heavy storm and woke up to it neon bright green. We bought some shock with algae killer in it and put 3 lbs in it. The next morning it looked even worse!! At the time we didn't have any extra money to do anything so we waited a week ( so by now its dark green with tadpoles looking like a swap lol). This time i found some liquid chlorine pretty cheap so i bought 4 gallons. That night i put 2 gallon in the pool. The next morning it was light green instead of dark. I am thinking awesome this is working so that night i put the other 2 gallon in. Woke up the next morning to it being blue cloudy water. I tested it and it said the alkalinity and ph was low. I read that i could baking soda so i bought a 12 lbs bag and put it in there yesterday. woke up this morning and u could finally see the bottom. I noticed there was some green spots on the bottom , a lot in the middle, and assumed its algae. We back washed it and then went out in about an hour and put 2 more gallon of liquid chlorine in it ( cause the strips say everything but chlorine is fine) and it was green again. Just by back washing it! thought i was finally on my way to a swimmable pool but now i am so dishearted i might just call it quits. Please someone help me but also remember i am new to this so i don't know as much as most.
