Looking pretty good Dave. With a CYA of 30, I'd watch the FC to ensure it stays ideally between 4-6 and ensure it doesn't drop below 2 as seen on the [FC/CYA][/FC/CYA]. If your water gets cold in the winter, you can just stick with bleach until the spring and leave your CYA at 30. If your water temp doesn't drop below 60 and you elect to use the SWG, then you can increase the CYA to 70 when you are ready. Thanks for using the forum. Have a nice weekend.
