Hello all
i am new to pools and this one came with the house and i am not sure of its maintenance history. It is 10 years old, fibreglass, 20,000 gal, cartridge filter. The heat pump has been removed - it had a leak and likely the source of copper. The house water is from a well and has been tested showing no copper The pool water has .4 ppm copper, .1 Iron - according to the store and they cannot test for Maganiez The pool is stained brownish. It was advised by the manufacturer to add 10lbs of cytric acid - amazingly we had a new pool in hours. Then the fun started. We added sequestering agent and within days clouding started, we added and agent to the filter to clear it and this did not do much but eventually it cleared up. We then started to add chlorine- slowly and within days the staining started to come back.
we have now been through this process using different products and following posts on this website and drained off 1/4 of the water, cleaning filters etc but without success. Using the last sequestering product the instructions said to shock to engage the chelating - we now have a green pool and the stain has reappeared worse then before. The though was perhaps the algicide HTH Algi gard 10 that was put in on the last round was a contributor but the manufacturer said there is no copper in it
we are planning to use citric acid, dump another 1/4 of the water, add a Culator pack Shop - CuLator Metal Eliminator and Stain Preventer for Pools and Spas. to grab the metal, get the ph back up, then add chlorine and hope for the best. I see the hardness is low, phosphates high and will need to tackle that
thoughts or suggestions would be helpful
