Very well done, but the water, gravel and media bugs do not survive that long without feeding so whenever i do this (I do it the same way you have) I chuck in suicide squad, generally the cheapest hardiest fish i can get they keep the media and gravel bugs have until the rest of the tank catches up.

Why do you want to lower the ph?

If you put a good thick backing on the tank you can put it next to a window, mines directly in front of a window, but I live in England and the sun don't really shine.

As for the mollies and .3 or whatever it is ph wont make a difference.
