Pod farm

[Redbird5]

On October 1st I started my pod farm,oj bottle rinsed out, added fresh salt water, a gentle ait bubbler and fed phyto plankton every Monday. About the middle of the month I added an old sponge from my aquarium. I see no pods, I know they're small, I'm wondering if they died.
Any advice for the next attempt?

Use your magnetic glass cleaner to clean the tank. Put magnet in a container with chaeto, flow and light. Rinse and repeat.

Phyto would really help as well.
