Just a quick question; At the end of last year I had the sand base re-leveled and I refilled the pool. At that time I just added CYA and nothing else until the end of the season. I used liquid chlorine for the last few weeks. When I opened the pool last weekend, I added salt to the pool and retested. Today my CYA is 60, Salt is 3500ppm, Total chlorine is 3.5 and my Total alkalinity is 60. Pool temp is 62 degrees. With A SWG setup, where should my numbers be?

These levels are designed for outdoor residential pools chlorinating with bleach or a SWG, and will need adjustments when used in other situations. Liquid chlorine is the same as bleach, and cal-hypo users can also use the bleach recommendations as long as you monitor your CH level.
There are some instances such as having an indoor pool, high TA or high CH fill water, lots of direct sunlight, fresh plaster, or having pH increasing rapidly you should expect to need some adjustments to these recommendations. For advice on what would be ideal for your pool please ask on the forum.
