Be very careful with the pucks. It is amazing how fast the CYA comes up when using them and pretty soon you have slimy walls and cloudy water. One 6Kg bucket of 3 inch pucks raised CYA on my new fill from 0 to 50 and, with the air and the water so warm, it only took about a month to empty the bucket. Had I not switched to liquid chlorine I'd be in big trouble by now.
