Questions about spa blower and closing.

[Poollover4]

1. When closing the pool do we need to blow out the spa air blower line and if so how to do it?
2. And another question which I know gets a lot of attention here. The closing instructions say to lower water below the return line and then refill ( I have solid cover) but it would cause significant change in water chemistry. Should I just blow out the lines and add antifreeze to skimmer/returns?

Blow out the spa return lines and then run the blower for a minute to blow it out.

You can do it either way.
