Self-admitedly, I know very little about sumps. First one I ever had was on my first saltwater tank, and it came with it. However, I'm pretty sure the toilet flushing isn't quieter than the set up had, so I am starting sompletely from scratch.
Take, if you will, a 54g bowfront with a 3" vertical hole in the back-right-corner-side (if you are facing the tank), with the bottom of the hole located 8.5 inches below the glass. 15g sump underneath the stand.
What do I need to plumb this into a pump? What size pump (will a 900gph be sufficient)? How can I make it as quiet as possible?
Tempered glass on the bottom - drilling there is not an option.
Thanks.
