I opened my pool for its second season. I topped off the water with well water from my hose. I now realize I should’ve filtered it as it was filling my pool. All was good for the first few weeks, just added shock and the water cleared up pretty fast. I thought I was keeping up with it but as the temperatures rose I noticed some algae appearing on the walls. I brushed during the day and doubled the dose of shock every night for 3 days. The water didn’t improve at all. I used a green to blue product, followed all instructions and used a flocculant. I ran the filter constantly. After another 2 days still sitting with green water. I took a sample in to a local pool store to be tested. Total chlorine was 2.99 ph 6.4 total alkalinity 14 and large amount of copper at 1.2. They told me any algae in the pool is most likely dead and the copper is the main concern and the cause for the color of the pool. They sold me a bottle of stain remover for the metal and told me to get the ph level up to normal. I first got the ph level up and the water turned from a darker to lighter green. Then I added the bottle of stain remover and ran the filter. 30 hrs later nothing has changed. I wen back to the store and the levels were still the same except for the ph level up to 7.5. They told me to try another bottle of the same remover. I added that and another 35hrs has passed while filter running and still have not seen any improvement to the water. It’s a cloudy light green color.
