New Tank Setup Tricks Needed

Hi!

I have recently set up 5 new planted tanks from scratch... three 10g, one 25g, one 150g.

Of the 5 new tanks I have been met with 4 BGA attacks of various sizes. In one of those four I also have the complex hair algae that has multiple "limbs."

Of course these things will go away using EI in time.

However, how do I set up a tank and avoid this problem in the first place? I generally do slower growing plants, so I'm wondering if I need to stuff some stem plants in there to help get the intake going faster. But I'd rather not have to. There has to be a trick or two I can employ to avoid this...

Thanks!
