Question about refugium light timing and cope pods

[r212019]

So im looking to have my sump light turn on when my main lights turn off to help with the ph swing. At what point should the refugium turn on? When the whites go off? When the blues go off?

Here is a pic of my lighting schedule

2nd question- how do i get the cope pods growing in my sump up into my main tank? I have chaeto growing and there is a bunch of pods in there. The section where the chaeto and pods are growing has a sponge that seperates the return section of the sump so i doubt many r getting thru the sponge. If i ran a little tube from the chaeto section down the side of rhe sponge into the return section, do you think pods would get thru the tube and then sent up into the main tank from the return pump or is that just a silly idea.

Please help, suggestions and ideas.
