I have a 24' round above ground pool, 25 gage vinyl liner, 2.5 hp pump, aquabug vaccuum. I started converting it from baquacil to chlorine 2 weeks ago. I went to the local pool store and they have been telling me what to do according to testing the water. First they said to put in a bottle of FLIP IT. Did that. Took another sample over and they said bacquacil was gone so time to balance. The first week they said put 2 lbs of shock in daily and run the filter 24/7. did that, cleaning the cartridge filter off daily. The pink goo was everywhere. The water turned brown and then green. Saturday I took more water over there to test and they told me to put 21 lbs of alkalinity, 10 lbs of calcium and 9 lbs of shock in three treatments every six hours. Did that. Water is still really green. When we put the shock in, the water turns a funny brown/green color and it gets stuff floating around on top of the pool. It is testing 7.8 ph, 180 alkalinity, 3 total chlorine and 0.5 free chlorine and very low reading on the stabilizer. I don't know what else to do. My husband is threatening to get rid of the pool. Do you have any suggestions?
