I'm moving this to the correct section of the forum where it will get more views.

Whenever you make a new thread, try and put it in the correct forum sub-section. The top section, "News and Notes from PoolDoc" is for us to use to put out announcements, etc., rather than for members to post questions in.

Thanks. Hope you have a good swim season!

(I am going to move both of your threads for you.)
