Terry,
I find that a ladies knee-high stocking works best for adding CYA. It seems to dissolve faster, and the open end of the stocking acts like a string to hang the stocking in front of a return..
I fill the end of the stocking with CYA and tie a knot into the open end.
I have a 1 x4 about 3 feet long that has a notch in one end and an old pool chemical bucket that it filled with water. I set the board over the top of a return and then drop the knee-high full of CYA, through the notch and into the water, I can then adjust it up and down to be in front of a return. I put the bucket of water on the board and over the knot, which holds the knee-high and board in place...
I suggest that you initially shoot for a high FC than you want and then slowly bring it down by adjust the SWCG's output or pump run time.. It is very easy to adjust down, and much harder to adjust up. I always recommend starting high... In your case I would target 8 ppm to start with..
Thanks,
Jim R.
