The Marineland LED
Bubble wands are awesome. I have a blue one that was in my 30 gal
right next to my pillow, and it never bothered me. Right now it's being used as moonlights in my sw
tank without the air. It turns out that it's a very versatile product, as it is suctioned to the underside of the lid. As for the cheap Wal-mart pump, I have 3 on my fw
tanks that run 24/7. They are quiet, and don't falter a bit. I swear by them. They only drawback is they are not adjustable.
