Coming to the end of the best season ever in the 25years I have had my 24ft. round AGP. I replaced the liner the first of June (3rd liner in 25yrs.) I first releveled and then covered the bottom with the pink 1/2 inch. foam insulation, double taping the seams. New cove also. This time I did the BBB method right from the start. Filled the pool with my well water which has clear water iron very bad, turns rust coloured as soon has the air and bleach hit it. I put in 4 boxes of Borax soon after filling. The Borax seemed to sequester the rust and make it drop to the bottom. I vaccumed to waste 2 times and water has been sparkling clear ever since. To date I have used 26 gal. of 12.5% bleach, 56oz of stabilizer, 4#s of 1inch chlorine tabs., 16oz. of 60% algecide,7 boxes of Borax and almost 4gal. of muratic acid. Absolutly no water problems, always very clear. We have had 18 days of 90 degree heat and very high humidity. While the humidity was high(>75%), I didn't have to add much make up water at all. Now that it is cooler and less humid, I am adding 2" a week. I have a 300 gallon plastic tank that I put my make up water in first, with some bleach. I let it sit for 3 or 4 days and the rust drops to the bottom so I can decant the clear water off of the top so I don't have to vacuum to waste to get rid of the rust.
